Answer: The only factor of 13 and 80 is 1.
Step-by-step explanation:
Factors of 13: 1, 13.
Factors of 80: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80.
The only factor they have the same is 1.
0.7154 is the product for 0.98×0.73
For this case we have the following functions:
f (x) = 36 + 4x
g (x) = x2 + 15
By matching both functions we have:
f (x) = g (x)
36 + 4x = x2 + 15
Rewriting we have:
x2 + 15 - 4x - 36 = 0
x2 - 4x - 21 = 0
Solving the polynomial we have:
(x-7) (x + 3) = 0
x = -3
x = 7
Taking the positive root we have:
x = 7
