Answer:
C. 74 sqft
Step-by-step explanation:
The bottom has a surface area of 4ft * 5ft = 20sqft
Theres two 3ft x 5ft sides and two 3ft x 4ft ones.
2 * 3ft * 5ft + 2 * 3ft * 4ft = 2 * 15sqft + 2 * 12sqft = 30sqft + 24sqft = 54sqft
Total surface of the outside is thus
20sqft + 54sqft = 74sqft
Answer: 7x + 4 y = 2
9x - 4y= 30
-------------------
16x / = 32
x= 32:16
x=2
Step-by-step explanation: 7x+4y=2
7*2 + 4y=2
14 +4y=2
4y= 2-14
4y= -12
y= -12 : 4
y= - 3
