Answer:
52 cm²
Step-by-step explanation:
A=2(wl+hl+hw)=2·(2·3+4·3+4·2)=52
A=3B
4.35A+5.40B=780.95
Substitute 3B into A for the second equation:
4.35(3B)+5.40B=780.90
13.05B+5.40B=780.90
18.45B=780.90
B=42.33
Plug into equation 1:
A=3B
A=3(42.33)
A=126.98
You need to find the area of this
<span>|5x - 1| < 1
-1 < 5x - 1 < 1
-1 + 1 < 5x < 1 + 1
0 < 5x < 2
0/5 < x < 2/5
0 < x < 2/5

Find out how far Molly walks in 1 minute.
4/70 = 0.057 miles
In 100 minutes,
0.057x100 = 5.714 miles
Rounded to the nearest tenth, 5.7 miles.
Hope I helped :)
