Answer:
One of the sides of the kitchen is 12
Step-by-step explanation:
We know that this is a square space, which means both sides are the same length. So, from that we know (something) x (something) = 144.
12 is the only number that works, 12 x 12 = 144.
Her book was 10 days late. D = days. The equation is .25(4) + .30d = 4.00. First you multiply .25 • 4 to get 1. Then you subtract 1 from both sides and get .30d = 3. Next you divide both sides by .30 to get d = 10.
subtract 6 from the 21x+6. Then divide by 21. The answer is going to be -6/21
Answer:
8x^3-7x^2-11x+9
Step-by-step explanation:
(8x^3-5x-1)-(7x^2+6x-10)
remove unnesasary ( )
8x^3-5x-1 -(7x^2+6x-10)
the distribute
8x^3-5x-1 -7x^2-6x+10
combine like terms
8x^3-11x+9-7x^2
use the communative property to reorder the equation
8x^3-7x^2-11x+9
