Area = length *width
A = x²
3x² = (x+10)(x+12)
3x² = x²+10x+12x+120
3x² = x²+22x+120
3x²-3x² = x²+22x+120-3x²
0 = -2x²+22x+120
Factor to solve for x:
-2(x²-11x-60)
(x+4)(x-15)
x = -4 & x = 15 but we can't have a negative length so we eliminate 4. The length of the square is 15 cm.
16% porque all you have to do is multiply 40 by 4% 0.04
All of the answer choices except B would be correct for this problem.
Answer:
<em>Eunice 3510; Suin 7020</em>
Step-by-step explanation:
<em>Eunice bought 585 beads.</em>
<em>Jennifer bought 6 times more than Eunice</em> but half of the total of beads Suin bought.
Eunice: 6 * 585 = 3510
Jennifer bought 6 times more than Eunice but <em>half of the total of beads Suin bought.</em>
<em>Suin: 3510 * 2 = 7020</em>
