Answer:
n = {-1, 7}
Step-by-step explanation:
8n² - 56 = 48n
Subtract 48n from both sides
8n² - 48n - 56 = 0
Divide both sides by 8
n² - 6n - 7 = 0
Factor
alternately use the quadratic equation or complete the square
(n - 7)(n + 1) = 0
n = {-1, 7}
Answer:
42°
Step-by-step explanation:
This is right triangle and sum of 2 angles is 90°:
y+48°=90°
so y= 90°- 48°= 42°

Answer:
f(4) - g(3) = 28
Step-by-step explanation:
f(x) = 8x + 10
f(4) = 8(4) + 10
f(4) = 32 + 10
f(4) = 42
g(x) = 6x - 4
g(3) = 6(3) - 4
g(3) = 18 - 4
g(3) = 14
f(4) - g(3)
= 42 - 14
= 28
