3x - 3 = root^2 of 3x^2 + 177 What is the sum of all the solutions to the above equation? A - 11 B) -3
C) 3
D) 7
We start by isolating the square root on one side of the equation:
3x - 3 = sqrt(3x^2 + 177)
Squaring both sides of the equation gives:
(3x - 3)^2 = 3x^2 + 177
Expanding the left-hand side gives:
9x^2 - 18x + 9 = 3x^2 + 177
Simplifying gives:
6x^2 - 18x - 168 = 0
Dividing both sides by 6 gives:
x^2 - 3x - 28 = 0
We can now solve for x using the quadratic formula:
x = (3 ± sqrt(3^2 + 4128)) / 2
x = (3 ± 7) / 2
Therefore, the solutions are x = -2 and x = 5, and their sum is -2 + 5 = 3.

In the game between Alphas and Betas the points of Alphas in the score
were in ratio 20 : 100 to the sum of points of both teams when Alex
substituted Appolo. Alex instantly scored his first point after that made
an uninterrupted sequence of hits before his reverse substitution. When
he was leaving the ground the ratio of the score of Alphas to all the
scored point in the game was 50 : 100. What ratio of all the points scored
up to that moment were Alex hits?
The ratio of all points scored up to the moment when Alex left the ground was 25 : 100. This means that out of all the points scored, 25% were Alex's hits.
What is ratio?Ratio is a comparison between two or more numbers. It is usually expressed in the form of a fraction, with the numerator being the first number and the denominator being the second number. Ratios can also be expressed in terms of a percentage or a proportion. Ratios help to compare two or more values and can be used to indicate relationships between different parts of a system. For example, if the ratio of apples to oranges is 2:3, then for every two apples, there are three oranges.
The reason for this is that when Alex entered the game, Alphas had a score of 20 points out of a total of 120 points. After his reverse substitution, Alphas had a score of 50 points out of a total of 100 points. This means that Alex scored 30 points in total during his time in the game. Therefore, the ratio of Alex's hits to the total points scored is 30 : 100, or 25%.
This shows the impressive contribution that Alex made in the game. Despite playing for a relatively short period of time, he was able to score a quarter of all the points in the game. This highlights Alex's skill and shows what a difference an individual player can make in a team sport.

For the following exercises, decide if the function continuous at the given point. If it is discontinuous, what type of discontinuity is it?
Both the limits are equal to -1, which means the function is continuous at x=1. Therefore, there is no discontinuity at x=1. So, The function is continuous at x=1.
To determine if the function is continuous at x=1, we need to evaluate the left and right limits of the function at x=1 and see if they are equal.
Left limit as x approaches 1:
\lim_{x\to 1^-}\frac{2x^2-5x+3}{x-1} = \frac{2(1)^2-5(1)+3}{1-1} = \frac{0}{0}
Right limit as x approaches 1:
\lim_{x\to 1^+}\frac{2x^2-5x+3}{x-1} = \frac{2(1)^2-5(1)+3}{1-1} = \frac{0}{0}
Since both limits are indeterminate forms of 0/0, we can use L'Hopital's Rule to evaluate them.
Taking the derivative of the numerator and denominator of the original function, we get:
\lim_{x\to 1^-}\frac{4x-5}{1} = -1
\lim_{x\to 1^+}\frac{4x-5}{1} = -1
Both limits are equal to -1, which means the function is continuous at x=1. Therefore, there is no discontinuity at x=1.

A vector u and a set S are given. If possible, write u as a linear combination of the vectors in S. U = [3], S= {[1], [2], [-2}}
[8] {[2] [3] [-5]}
Therefore, one possible way to write vector u as a linear combination of the vectors in set S is:
u = [2] + [3]
To write vector u as a linear combination of the vectors in set S, we need to find scalars a, b, and c such that:
u = a[1] + b[2] + c[-2]
Substituting the given values of u and the vectors in S, we get:
[3] = a[1] + b[2] + c[-2]
To solve for the scalars a, b, and c, we can set up a system of equations:
3 = a + 2b - 2c
Since we only have one equation and three unknowns, there are infinitely many solutions to this system. One possible solution is:
a = 1, b = 1, c = 0
Substituting these values back into the equation, we get:
[3] = 1[1] + 1[2] + 0[-2]
Therefore, one possible way to write vector u as a linear combination of the vectors in set S is:
u = [1] + [2]
Similarly, for the second set of vectors, we need to find scalars d, e, and f such that:
u = d[2] + e[3] + f[-5]
Substituting the given values of u and the vectors in S, we get:
[8] = d[2] + e[3] + f[-5]
To solve for the scalars d, e, and f, we can set up a system of equations:
8 = 2d + 3e - 5f
Since we only have one equation and three unknowns, there are infinitely many solutions to this system. One possible solution is:
d = 2, e = 2, f = 0
Substituting these values back into the equation, we get:

Quadrilateral ABCD is inscribed in this circle.
What is the measure of angle A?
The measure of angle A is 85^o.
What is a quadrilateral?A quadrilateral is any form of plane figure which is bounded by four straight sides. Examples include: square, rhombus, rectangle trapezium etc. Each example of quadrilateral has differentiating properties.
The given quadrilateral ABCD inscribed in the circle has the shape of a rhombus. So we have:
the measure of opposite internal angles of a rhombus are congruent, so that;
x + (2x + 1) + 148 + (2x + 1) = 360
5x + 150 = 360
5x = 360 - 150
5x = 210
x = 210/ 5
= 42
x = 42^o
Thus measure of angle A = (2x + 1)
= 2*42 + 1
= 85^o

helloo!! i need help figuring out the like terms in this list. thanks! :)
The like terms on the list are given as follows:
[tex]\sqrt{2}, -3\sqrt{2}, 5\sqrt{2}, \sqrt{50}[/tex]
What are like terms?Like terms are terms that share these two features:
Same letters. (algebraic variables).Same exponents.If two terms are like terms, then they can be either added or subtracted.
In the case the terms are roots, they have the same root.
The square root of 50 is given as follows:
[tex]\sqrt{50} = \sqrt{2 \times 25} = 5\sqrt{2}[/tex]
Hence the like terms are given as follows:
[tex]\sqrt{2}, -3\sqrt{2}, 5\sqrt{2}, \sqrt{50}[/tex]
There are no terms with 3 or 5 on the root, hence the other two terms have no like terms.

geoff is investigation fractions of the form (1)/(n), where n is an interger from 2 up to and including 20. How many of these fractions are equivalent to terminating decimals
The final answer are 7 fractions of the form (1)/(n), where n is an integer from 2 up to and including 20, that are equivalent to terminating decimals.
Geoff is investigating fractions of the form (1)/(n), where n is an integer from 2 up to and including 20. To find out how many of these fractions are equivalent to terminating decimals, we need to understand what makes a fraction equivalent to a terminating decimal.
A fraction is equivalent to a terminating decimal if the denominator (the bottom number) is a power of 10 (10, 100, 1000, etc.), or if it can be reduced to a fraction with a denominator that is a power of 10. In other words, the denominator must only have factors of 2 and/or 5.
So, we need to find out how many of the numbers from 2 to 20 have only factors of 2 and/or 5.
These numbers are:
- 2 (2^1)
- 4 (2^2)
- 5 (5^1)
- 8 (2^3)
- 10 (2^1 * 5^1)
- 16 (2^4)
- 20 (2^2 * 5^1)
Therefore, there are 7 fractions of the form (1)/(n), where n is an integer from 2 up to and including 20, that are equivalent to terminating decimals.

You're welcome.
Answer:
8+3(5-7)=-2
You will use the"Bracket Of Division Multiplication Addition and Subtraction(BODMAS)" method. Hence solve the one in the bracket first. So it's going to be 5-7 which is -2.Then you continue with the multiplication of 3 by the -2 you got making -6. Finally add the 8 to the -6 making 2.
