3 and four sevenths bcs 25divided by seven is 3r4
The sum of the measures of the angles is 180 degrees.
75 + -5w + 125 + 4w + 85 = 180
Combine like terms.
285 - w = 180
Subtract 285 from both sides.
-w = -105
Divide both sides by -1.
w = 105
Answer:
g(f(- 2)) = 91
Step-by-step explanation:
Evaluate f(- 2) then substitute the value obtained into g(x), that is
f(- 2) = - 2 + 7 = 5 , then
g(5) = 4(5)² - 9 = 4(25) - 9 = 100 - 9 = 91
Rx = 30...divide both sides by r
x = 30/r <==
