-5(1 - 5x) + 5(-8x - 2) = -4x - 8
-5 + 25x - 40x - 10 = -4x - 8
25x - 40x + 4x = -8 + 10 + 5 = 7
-11x = 7
x = -7/11
Answer:
b = -80
Step-by-step explanation:
-16 = 0.2b
Divide both sides by 0.2
We have , -16/0.2 = 0.2b/0.2
Therefore, b = -80

Answer:
x² + x - 12 = 0
Step-by-step explanation:
Given the solutions are x = - 4 and x = 3, then the factors are
(x + 4) and (x - 3) and the equation is the product of the factors, that is
(x + 4)(x - 3) = 0 ← expand factors using FOIL
x² + x - 12 = 0 ← in standard form
