Answer:
work is shown and pictured
W = 20
<span>l = 2w = 40 </span>
<span>if l is increased by x, w is increased by 1/2x </span>
<span>A = l x w = (40 + x)(20 + 1/2x) = 1/2(40 + x)(40 + x) </span>
<span>A = (40+x)²/2</span>
Answer:
63 red marbles.
Step-by-step explanation:
Because the probability of drawing a red marble is 7/8, the number of red marbles = 7/8 * 72
= 7 * 9
= 63.
You would first divide 28 by 7.
28 / 7 = 4.
Now multiply 4 by 5.
4 X 5 = 20.
