Answer: H
Step-by-step explanation:
We can see this rectangular prism will have side lengths of 5, 3, 7.
So we can use the fact Surface Area = 2(lh+wh+lw) to get:
2(15 + 35 + 21) = 2(71) = 142
Answer:
They are proportional
Step-by-step explanation:
becaue the length of one of the square's sides is 1/4 the perimeter
Answer:
x = 14 D
Step-by-step explanation:
(18x + 36) / 3 = 6x + 12
6x + 12 = -16 + 8x
-6x . -6x
12 = -16 + 2x
+16 . +16
28 = 2x
/2 . /2
14 = x
2 rectangle shaped
1) Length = 160 mi ; Width = 40 mi
2) Length = 440 mi - 160 mi ; Width = 240 mi - 70 mi
1 triangle shape
1) base = 70 mi ; height = 440 mi - 160 mi
Area Rectangle 1 = 160 mi * 40 mi = 6,400 mi²
Area Rectangle 2 = 280 mi * 170 mi = 47,600 mi²
Area Triangle 1 = ((440 mi - 160 mi) * 70mi)/2 = (280mi * 70mi)/2 = 9,800 mi²
Total Area = 6,400 mi² + 47,600 mi² + 9,800 mi² = <span>63,800 mi²</span>
After demonstrating the procedure by algebraic means, the expression ![(2\sqrt[3]{12} )\cdot (3\sqrt[3]{2} )](https://tex.z-dn.net/?f=%282%5Csqrt%5B3%5D%7B12%7D%20%29%5Ccdot%20%283%5Csqrt%5B3%5D%7B2%7D%20%29)
