Answer:
x = 6
Step-by-step explanation:
HF = 4x + 9
EF = 5x + 3
Since FG is perpendicular to EH, ∆EFG and ∆HFG are congruent to each other.
Thus:
HF = EF
4x + 9 = 5x + 3 (substitution)
Collect like terms
4x - 5x = -9 + 3
-x = -6
Divide both sides by -1

answer = no it does not measure a rate
Simplify:
5x - 10
8
The equation will become 6/3+2(3)
-->6/3=2
-->Because of Order of Operation we will multiply the 2 and 3 before adding so 2(3) = 6
--> 6+2=8
