Solve x2 - 8x = 3 by completing the square. Which is the solution set of the equation?
A. (4 - √19, 4 + √19)
B. (4 - √11, 4 + √11)
C. (4 - √8, 4 + √8)
D. (4 - √3, 4 + √3)
Answer:
A.
Step-by-step explanation:
Step 1: Write equation
x² - 8x = 3
Step 2: Solve for x
Complete the Square: x² - 8x + 16 = 3 + 16Factor: (x - 4)² = 19Square root both sides: x - 4 = ±√19Add 4 to both sides: x = 4 ± √19Answer:
A
Step-by-step explanation:
because when doing these equations it is the same except one is positive and one is negative

my teacher wants me to solve does questions but in that way can you please help me:(
Answer:
1.) X = 1 2.) X = 7
Step-by-step explanation:
1.) 3x - 6 = 9
Subtract 6 on both sides
3x = 3
Divided 3 on both sides
X = 1
2.) -5x + 3x = 11 + 3
Put the like terms on both sides
-2x = 14
Divide both sides by 2
X = 7

The sum of 5 consecutive numbers is 70. Determine the value of the smallest number.
==========================================================
Work Shown:
x = first number
x+1 = second number
x+2 = third number
x+3 = fourth number
x+4 = fifth number
Note how the numbers are one after another. Consecutive numbers follow this pattern. For example: 6,7,8,9,10 are consecutive numbers. One number follows right after the other.
---------------
Add up those five expressions. Set the sum equal to 70 and solve for x
(x)+(x+1)+(x+2)+(x+3)+(x+4) = 70
(x+x+x+x+x)+(1+2+3+4) = 70
5x+10 = 70
5x = 70-10
5x = 60
x = 60/5
x = 12 is the first number and the smallest number
x+1 = 12+1 = 13 is the second number
x+2 = 12+2 = 14 is the third number
x+3 = 12+3 = 15 is the fourth number
x+4 = 12+4 = 16 is the fifth number
Check:
12+13+14+15+16 = 70
which confirms our answer
-----------------
You could use a guess and check method, but the algebraic approach is much more efficient.
"what value of x makes 5x+10=5(11-2x)
Answer:
5x + 10 = 5(11 - 2x)
5x + 10 = 55 - 10x
5x + 10x = 55 - 10
15x = 45
15x ÷ 15 = 45 ÷ 15
x = 3
so the answer is 3

What is the value of a in the equation 3 a plus b equals 54 when b equals 9?
Answer:-1/3b+18
Step-by-step explanation:
Let's solve for a.
3a+b=54
Step 1: Add -b to both sides.
3a+b+−b=54+−b
3a=−b+54
Step 2: Divide both sides by 3.
3a/3= -b+54

Multiply. 2√⋅5√⋅11−−√ Enter your answer, in radical form, in the box.
Answer:
√110
Step-by-step explanation:
The multiplication of the numbers √2, √5, and √11 is √110 after applying arithmetic operation.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.
It is given that:
The number expression is:
= √2. √5 . √11
From the definition of the arithmetic operation, the operation in which we do the addition of numbers, subtraction, multiplication, and division.
= √(2x5x11)
= √110
Thus, the multiplication of the numbers √2, √5, and √11 is √110 after applying arithmetic operation.

Tonisha has a lemonade stand. She has 31 dollars in expenses and wants to make at least 66 dollars per day. If x represents the amount of revenue from selling lemonade, an inequality to represent the amount of revenue she would need to generate would be:
Answer:
x-31(Greater than or equal to)66 -->x(greater than or equal to)97
Step-by-step explanation:
SHe wants to make a profit of 66, but with 31 bucks in expenses, this would need the revenue to be greater than 97 to cover the expenses and still make the profit

What is (4x - 5)(6x + 5) expressed as a trinomial?
Answer:
24x^2 -10x - 25
Step-by-step explanation:
24x^2 + 20x - 30x - 25
24^2 -10x - 25
Answer:
Simplifying
4x + -5 = 6x + 5
Reorder the terms:
-5 + 4x = 6x + 5
Reorder the terms:
-5 + 4x = 5 + 6x
Solving
-5 + 4x = 5 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation.
-5 + 4x + -6x = 5 + 6x + -6x
Combine like terms: 4x + -6x = -2x
-5 + -2x = 5 + 6x + -6x
Combine like terms: 6x + -6x = 0
-5 + -2x = 5 + 0
-5 + -2x = 5
Add '5' to each side of the equation.
-5 + 5 + -2x = 5 + 5
Combine like terms: -5 + 5 = 0
0 + -2x = 5 + 5
-2x = 5 + 5
Combine like terms: 5 + 5 = 10
-2x = 10
Divide each side by '-2'.
x = -5
Simplifying
x = -5

how do u evaluate variable expression
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression. Hope this helps! :)
