Hi there! :)

Solve for j(h(x)):
h(x) = x² + 4
j(x) = 4x - 1
Substitute in h(x) into "x":
j(h(x)) = 4(x² + 4) - 1
j(h(x)) = 4x² + 16 - 1
j(h(x)) = 4x² + 15
Solve at x = 2:
4(2)² + 15 = 4(4) + 15 = 31.
It should be for 5 hours if $30 is what they started with
I'm unsure of the question but this expression can be written as:
16 + x < 32.
This can be simplified to:
x < 16
Answer:
x = 17
Step-by-step explanation:
A triangle's sum is 180 degrees, hence
6x + 10 + x + 17 + 4x - 34 = 180.
11x + 10 + 17 - 34 = 180
11x - 7 = 180
11x = 187
x = 17
hope this helps and is right!! p.s. i really need brainliest :)
