Answer:
The Volume is equal to 2x^3-3x^2+2x-3
Step-by-step explanation:
Formula for the volume of a rectangular prism is V=WHL
We know that:
W=x-1
L=x+1
H=2x-3
So, V= (x-1)(x-1)(2x-3)
Simplify
(x^2+1)(2x-3)
2x^3-3x^2+2x-3
7, 9,11,13 odd integrates
H-5 = -30
Add 5 to both sides to get variable h by itself
h = -25
Yvonne ran up 12 flights of stairs.
Explanation:
Understand the situation:
Yvonne ran up 1/4 of the total stairs. Afterwards, she walked the REST of the stairs, which is said to be 9 STAIRS. HOW MANY flights of stairs IN TOTAL did she run up?
When she ran the REST of the stairs, it meant she ran the other 3/4 of stairs because:
1 - 1/4 = 3/4
To add someting, that means that the 9 stairs is 3/4 of the total stairs, so lets fins the total stairs using this information:
9 ÷ 3/4 = 12
LETS CHECK IF 9 IS REALLY 3/4 of 12:
12 x 3/4 = 9

Answer:
4 cm
Step-by-step explanation:
The square root of 144 is 12 (12 x 12 = 144) so we know our sides of the square are 12 cm²
12 / 3 = 4
()
The sides of the new square are 4 :)
Hope this helps and is correct, have a nice day! :D
