Answer:
Step-by-step explanation:
Face perimeter is
7.5 + 4(1.5) + 3(2.5) = 21 ft
Perimeter wall area
21(1.5) = 31.5 ft²
Face area (x2 for front and back)
2(7.5(1.5) + 2.5(1.5)) = 30 ft²
Total surface area
31.5 + 30 = 61.5 ft²
i think the answer is 1.05...im not 100% sure.
250 square inches if anything it looks most ideal
Answer:
5,600,000,000,000 (read "5 trillion, 6 hundred million").
Explanation:
5.6e12 is another way of writing scientific notation. This is the same as
5.6 x 10^12
The power of 10 tells us how many places to move the decimal. This means we move it 12 places. Since the exponent is positive, we are going to make the number larger; this means we move the decimal to the right. Moving it 12 places gives us
5,600,000,000,000
(9x⁴ - x²y² - 5y⁴<span>) - (3x</span>⁴ + 2x²y² - 7y⁴<span>)
</span>9x⁴ - x²y² - 5y⁴ - 3x⁴ - 2x²y² + 7y⁴
6x⁴ - 3x²y² + 2y⁴
