Answer: w =1 L=6
Step-by-step explanation:
What is Perimeter = 2 L + 2W
2L + 2B =14
L = 2W + 4
2(2W + 4) + 2W = 14
4W +8 +2W =14
6W=14-8
W=1
L=2W +4= 6
Answer:
a =5
Step-by-step explanation:
4a -3 = 2a +7
Subtract 2a from each side
4a-2a -3 = 2a-2a +7
2a-3 =7
Add 3 to each side
2a-3+3 = 7+3
2a=10
Divide each side by 2
2a/2 = 10/2
a =5
Volume is length time width time height
V = l x w x h
V = 3 x 12.5 x 8.4
V = 315 <<<This is the volume
Hope this helped!
<span>Answer:
We'll have to integrate the growth rate with respect to time, without forgetting the amount of area covered at the start.
A = 2010 + â« 8t1/2 dt (as t goes from 0 to 24)
A = 2010 + [(16/3) t3/2] (as t goes from 0 to 24)
A = 2010 + 627 = 2637 acres
We don't integrate the 2010 here because whatever effects of the passing of time have already taken place over that area. We just treat it as a constant and add it to the result of integration.</span>
Answer:
20 units
Step-by-step explanation:
The formula for the area:
A = bh × 1/2
B = 8 units
H = 5 units
8 × 5 = 40
40 × 1/2 = 20
