Answer:
b = 7
Step-by-step explanation:
- 4(2 - 5b) = 132
- 4 × 2 - 4 × (- 5b) = 132
-8 + 20b = 132
20b = 132 + 8
20b = 140
b = 140/20
b = 7
Thus, The value of b is 7

Answer:
Factors can be set to zero in order to find the solutions, which are the x-intercepts on a graph.
ex:
x^2 + 4x - 4
(x + 2)(x + 2)
x+2=0
x=-2
x+2=0
x=-2
-2 would be the only x-intercept on the graph.
Someone correct me if I'm wrong, thank you
It is not function as element of input (-2) has two image in output as function can be only many to one or one to one.
