Hello from MrBillDoesMath!
Answer: b = 4, h = 13
Discussion:
For a triangle with base b" and height "h, the area formula is
A= (1/2)bh.
In our case A = 26, h = 5b-7, so
26 = (1/2) b (5b-7). Multiply both sides by 2:
26*2 = b(5b-7) =>
52 = b(5b-7) =>
52 = 5b^2 - 7b => (subtract 52 from both sides)
5b^2 - 7b - 52 = 0. This factors as follows:
(b - 4) (5 b + 13) = 0 (use quadratic formula to find this)
so b = 4 and h = 5b -7 = 5*4 - 7 = 13
Thank you,
MrB
I think it will be B 610 and 820 but im not sure.
Hope This Helps!

Answer:
63.7999... (repeating) fps
Step-by-step explanation:
Feet per second (fps) per one (1) mph is 1.4666... repeating
so 43.5 * 1.46666... = 63.7999.. repeating
hope this helps:)
3+5=8
8^2 is 8×8 which equals 64.
The square of the sum of 3 and 5 equals 64.
C. A function can only have one y value for an x value
