First would distribute in the brackets and the equation you should have is 32x-8-44. from there combine the like terms, you should get 32x-52.
Formula: A = pi(r)^2
1/4(2)^2pi
1/4 * 4 pi = just pi
The area would be 3.14
Answer:
y = 1
x = -1
Step-by-step explanation:
- 4x + 11y = 15
2 = 2y
Find y from the second equation
2 = 2y
2/2 = 2y/2
1 = y
Substitute y into the first equation.
- 4x + 11y = 15
- 4x + 11(1) = 15
- 4x + 11 = 15
-4x = 15 - 11
-4x/-4 = 4/-4
x = -1
