Answer:
10
Step-by-step explanation:
By the geometric mean theorem,
- 4/a = a/25
- 100=a² (cross multiply)
- a=10 (square root both sides and take the positive solution)
Pretty sure it’s C sorry if wrong
We’ll subtract the exponent in the denominator from the exponent in the numerator, keeping the base the same. Cant be simplified, because the base of the expression in the numerator is y and the base of the expression in the denominator is x.

Answer:
156 miles
the equation would be L=54 + (D * 3)
L=54 + (43 * 3)
L=54+102
L=156
Step-by-step explanation:
since you add 3 miles each day, and it is going for 34 days
it would be 34 x 3= 102 so 102 miles.
BUT the road starts as 54 miles
so 54+102= 156 miles
