Answer:
Step-by-step explanation:
1) Evaluate the exponent:
2) Multiply the numbers:
= 20y + 3y -4(-2y)
= 20y + 3y + 8y
= 31y
In short, Your Final Answer would be 31y
Hope this helps!
Answer:
-2
Step-by-step explanation:
2x + 4 = x^2 + x - 2
x^2 + x - 2 - 4 - 2x = 0
x^2 - x - 6 = 0
(x - 3)(x + 2) = 0
x - 3 = 0 y = 2x + 4
x = 3 y = 2(3) + 4
y = 10
x + 2 = 0 y = 2x + 4
x = -2 y = 2(-2) + 4
y = 0
solutions are : (3,10) and (-2,0) <===
