Answer:
10.5
Step-by-step explanation:
Easy peasy
just subsitute I(x) for the x in the h(x) so
h(I(s))=-(2s+3)^2-4
distribute and simplify
h(I(s))=-(4s^2+12s+9)-4
h(I(s))=-4s^2-12s-9-4
h(I(s))=-4s^2-12s-13
Answer:
D
Step-by-step explanation:
Sum the three angle of triangle = 180
x + 53 + 60 = 180
x + 113 = 180
x = 180 - 113
x = 67
Answer: B(3)
Explanation: 12+9=21 so since 4+3 only equals 7, you plug in x as 3... since 7x3 is 21 that helps make the statement true bc both equations are equal.
