Answer:
pretty sure x is 60 because 60+25 is 80 and its the same as N so 80
Step-by-step explanation:
A) w * L = 112
B) 2w + 2L = 44
A) w = 112 / L then substituting this into B)
B) 2 * (112/L) + 2L = 44
B) 224 / L + 2L = 44
B) 224 + 2L^2 = 44L
B) 2L^2 -44L +224 = 0
L = 14
L = 8
Double Check
Width = 14 Length = 8
2*14= 28 2*8 = 16
28 + 16 = 44
14*8= 112
Correct!!!

Each of three people had 3 slices; 3 * 3 = 9
9 slices = 90%
Sally and her two friends ate 90% of the pizza.
Hope this helps.
Answer:
how can i help
Step-by-step explanation:
F(x) = 4x + 3
the domain: Df = R
g(x) = -2x + 5
the domain: Dg = R
Df = Dg therefore (f · g)(x) = f(x) · g(x)
f(5) = 4 · 5 + 3 = 20 + 3 = 23
g(5) = -2 · 5 + 5 = -10 + 5 = -5
(f · g)(5) = f(5) · g(5) = 23 · (-5) = -115
