Answer:
His error is multiplying by 4 sides as he thought it was total surface not lateral surface area- the final answer is 12
Step-by-step explanation:
He should have multiplied it by 3, because the 3 sides- not including the base- is what lateral surface area is. He originally did total surface area not lateral surface area so each sides area is 4m squared then you just multiply it by 3 and its 12
No because a triangle is 180 degrees and the following angles only equal to 165
Answer:
p>3
Step-by-step explanation:
<=> 3p - 9 - 5p > -3p - 6
<=> -2p + 3p > -6 + 9
<=> p > 3
Answer:
b
Step-by-step explanation:
(a - b)² = a² - 2ab + b²
(2x - 6)² = (2x)² - 2*2x *6 + 6²
= 4x² - 24x + 36
Answer:
8/15 x 5/8 = 1/3
2/9 x 3/4 = 1/2
Step-by-step explanation:
multiply the numerators and denominators together.
8/15 x 5/8 = (8 x 5)/ (15 x 8)
40/120
Simplify by dividing by 40. (GCF)
1/3

multiply the numerators and denominators together.
2/9 x 3/4 = (2 x 3)/ (9 x 4)
6/36
Simplify by dividing by 6. (GCF)
1/2
