You would answer square roots and powers in the step of Exponents. so if your equation included square roots you would solve them after parenthesis.
Answer:
10x³ + 12x² - 198x - 40
Step-by-step explanation:
Given parameters:
L(x) = 5x + 1
W(x) = 2x - 8
H(x) = x + 5
Unknown:
Volume = ?
Solution:
The volume of the body;
Volume = L x W x H
Insert the parameters and solve;
Volume = (5x + 1)(2x - 8)(x + 5)
Volume = (10x² - 40x + 2x - 8)(x + 5)
Volume = (10x² - 38x - 8 )(x + 5)
Volume = 10x³ - 38x² - 8x + 50x² - 190x - 40
Volume = 10x³ -38x² + 50x² - 8x - 190x - 40
Volume = 10x³ + 12x² - 198x - 40
First, determine the area of the floor of the new room by multiplying the dimensions in feet.
Area = (12 ft)(15.5 ft) = 186 ft²
Then, we convert the calculated area to yards
(186 ft²)(1 yd/ 3 ft)² = 20.67 yd²
Given that the supplier only delivered 20 yd², approximately 0.67 yd² of your floor will not have carpet.
I think it’s A i’m not 100% sure tho ❤️
It would be 5 Because a reflection doesnt change the value of the sides
