Answer:
a) 190
b)-189
Step-by-step explanation:
4a)
-2y+7(4+8y)=
-2y+(7·4)+(7·8y)=
-2y+28+(7·8y)=
-2y+28+(7·24)
-2y+28+168=
-6+28+168=
22+168 solve
4b)
-5w-4(6t+5)
-5w-4(36+5)
-5w-(4·41)
-5w-164
-25-164 solve
The values that make the denominator zero are not in the domain.
x²- 4x - 12 = 0
(x - 6)(x + 2) = 0
