The 2 numbers are 8 and 9.
8^2=64
9^2=81
<span>81+64=145</span>
(f*g)(x) = (x-4)(2x+1) = 2x² + x - 8x - 4 = 2x² - 7x - 4
(f-g)(x) = x-4 - (2x+1) = (x-4)-2x-1 = -x - 5
(f+g)(3) = 3 - 4 + 2*3 + 1 = -1 + 6 + 1 = 6
C is the correct answer for 19
Answer:
5
Step-by-step explanation:
Divide 55 by 5/7, and you’ll get x.
55/(5/7) = 55*(7/5) = 11*7 = 77 = x
