Answers
Answer:
B
Step-by-step explanation:
2(X+4)=6x+7-4x+1
2x+8=6x+7-4x+1
2x+8=6x-4x+7+1
2x+8=2x+8
2x-2x=8-8
0=0
answer=0
Answer:
B
Step-by-step explanation:
2(x + 4) = 6x + 7 - 4x + 1 ← distribute parenthesis on left side
2x + 8 = 2x + 8
since both sides of the equation are the same then any real value of x will be a solution to the equation, that is
the equation has infinitely many solutions
Kris thinks of a number. He divides by 14, subtracts 5. The number is the same as he thought of. What’s the number?
Answers
Answer:
0
Step-by-step explanation:
If you divide 14 by 0 it will be 0, and you subtract by 5 it will still be 0.
Let x be the number Kris thought of. Then:
x/14 - 5 = x <=>
x/14 = x+5 <=>
x = 14x+70 <=>
-13x = 70 <=>
x = -70/13 <=>
x = −5,3846

1. A ball is thrown straight up from the top of a building that is 400 ft high with an initial velocity of 64 ft/s. The height of the object can be modeled by the equation s(t) = -16t^2 + 64t + 400. (solve step by step pls)
2. In two or more complete sentences explain how to determine the time(s) the ball is higher than the building in interval notation.
Answers
The interval for the given situation is (0, 4).
Given that, height = 400 ft, initial velocity of 64 ft/s and the equation s(t) = -16t² + 64t + 400.
What is an initial velocity?Initial velocity is the velocity at time interval t = 0 and it is represented by u. It is the velocity at which the motion starts. They are four initial velocity formulas: (1) If time, acceleration and final velocity are provided, the initial velocity is articulated as. u = v – at.
To find the interval in which the ball is higher than the building, solve the inequality h(t) > 400. The inequality is easily solved by subtracting 400 so the comparison is to zero, factoring the expression involving t, and identifying the time interval in which the signs of the factors are the same.
-16t² +64t +400 > 400
⇒ -16t² +64t > 0
⇒ -16t (t -4) > 0
⇒ t=0 and t-4=0
Both factors will have negative signs on the interval (0, 4).
Therefore, the interval for the given situation is (0, 4).

Based on the measurements shown on triangle ABC, AB must be?
Answers
Answer: B. 7 and 10 ft
Step-by-step explanation:
The first thing to do is to look at the triangle’s angles. One of them is missing right? So you need to find that missing angle. All the angles in a triangle add up to 180 degrees. Therefore you need to add 68 and 47. Your total must be subtracted by 180.
Your problem will look like this
68+47=115
180-115=65
Your missing angle is 65The angle correspond to the sides. You need to look at the opposite of the angle to figure out the number of the side.
For example Angle A opposite = 7
Angle B opposite is 10
notice that Angle B degree is 68 which is the largest degree. And Angle A degree is 47 which is the smallest degree.
The largest degree will always be equal to the largest side
The smallest degree will equal to the smallest side

the sides of a triangle are 5:8:10 and it's perimeter is 23 cm. find the area of triangle.
Answers
Answer:
19.81cm^2
Step-by-step explanation:
To solve this, you need to use Heron's formula. Heron's formula solves for the area of a triangle given 3 sides defined as a, b, and c, as well as the perimeter. In this formula, p is half of the perimeter. The formula is:
sqrt(p*(p-a)*(p-b)*(p-c))
Plugging the values into this formula gives 19.81cm^2.

m∠BCD = 145° ⇒ m∠BCA = 180° - 145° = 35°
From ΔABC:
m∠ABC + m∠BCA + m∠BAC = 180°

Correctly multiply (3x + 7) (7x + 5)
Then find the sum of the coefficients of your solution.
Answers
Answer:
The sum of the coefficients is 85.
Step-by-step explanation:
(3x + 7)(7x + 5)
3x * 7x is 21x^2
3x*5 is 15x
7 * 7x is 49x
7 * 5 is 35
21x^2 + 15x + 49x + 35
So the answer is 21x^2 + 64x + 35
Add the coefficients: 21 + 64 = 85
