Answer:
9x + 36 = 10
Step-by-step explanation:
Given
x + 3 = 
Multiply by the lowest common multiple of 4 and 6, that is 12
12 ×
x + 12 × 3 = 12 ×
, that is
9x + 36 = 10 ← equation without fractions
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.
350 / 28 = 12.5 gallons, so 13 gallons needed
13 X 2.5 = $32.50
