Answer:
Area=77
Step-by-step explanation:
P=36
P=2l+2w
l=w+4
P=2(w+4)+2w
P=2w+8+2w
P=4w+8
36=4w+8
28=4w
w=7
l=7+4
l=11
A=lw
A=77
Calculate h(1):
h(a) = 2a - 4 → h(1) = 2(1) - 4 = 2 - 4 = -2
Next calculate g(-2):
g(a) = a - 5 → g(-2) = -2 - 5 = -7
<h3>Answer: g(h(1)) = -7</h3>
We need a picture or something..
The cafeteria sold 41 corn chips and 80 potato chips.
Step-by-step explanation:
Let,
Corn chips = x
Potato chips = y
Price of corn chips = $0.80
Price of potato chips = $0.60
According to given statement;
x+y= 121 Eqn 1
0.80x+0.60y=80.80 Eqn 2
Multiplying Eqn 1 by 0.80

Subtracting Eqn 2 from Eqn 3

Dividing both sides by 0.20

Putting y=80 in Eqn 1

The cafeteria sold 41 corn chips and 80 potato chips.
