Answer:
k = 2
Step-by-step explanation:
Based on the right triangle altitude theorem, thus:
4 = √(k*8)
Square both sides
4² = k*8
16 = 8k
Divide both sides by 8
16/8 = 8k/8
2 = k
k = 2
A correct possibility could be $37.50 because 37.50 x 2 + 4 = 79
Answer:
I think it should be 32
Step-by-step explanation:
11 x 7= 77
9 x 5=45
77-45=32
