We need to make an equation. The equation used to find perimeter is 2L+2W=A
We know that the area is 24 cm. We also know that the length is 3 cm more than its width: L=3+W; let's plug that equation in for L.
2(3+W)+2W=24; let's simplify the parenthesis. 6+2w+2w=24 6+4w=24; subtract 6 from both sides. 4w=18; divide both sides by 4. W=4.5
Let's find the length if the width is 4.5.
4.5+3=7.5; So, the length is 7.5 and the width is 4.5. Let's check. 2(7.5)+2(4.5)=15+9=24
So, the length is 7.5 and the width is 4.5.
Answer:
2<d<8
Step-by-step explanation:
I have the same packet
Answer: If it flows at 60 in 1/5 of an hour or twenty minutes it will flow 300 gallons in an hour which is the same as part b so part c is both flow at the same rate
8 x 2 x 5 = 80
So the volume of the prism would be 80 cubic centimeters
