Answer:
9
Step-by-step explanation:
Equation 1) y = x² + 10x + 11
Equation 2) y = x² + x - 7
Subtract equations from one another.
9x = 18
Divide both sides by 9.
x = 2
Plug in 2 for x in the first equation.
y = x² + 10x + 11
y = 2² + 10(2) + 11
Simplify.
y = 4 + 20 + 11
y = 35
Plug in 35 for y and 2 for x in the first equation to check your work.
y = x² + 10x + 11
35 = 2² + 10(2) + 11
35 = 4 + 20 + 11
35 = 24 + 11
35 = 35
So, we know that our answer is correct! :))
x = 2, y = 35
Answer:
a = 10.5 feet
Step-by-step explanation:
Given that,
The area of a square room, A = 110.25 ft²
We need to find the side length of the living room. Let the side be x.
We know that,
The area of a square, 
So,
So, the side length of the living room is equal to 10.5 feet.
