Answer:
14 cm, 18 cm, 20 cm
Step-by-step explanation:
7x + 9x + 10x = 26x
equation: 26x = 52
divide each side by 26: x = 2
7 * 2 = 14
9 * 2 = 18
10 * 2 = 20
check if answer is right: 14 + 20 + 18 = 52
I hope this helped, please mark Brainliest thank you so much!!

Answer:
x^3+2x^2-x-2=(x+2)(x-1)(x+1)
The other two factors are x-1 and x+1
Step-by-step explanation:
Use synthetic division:
x^3+2x^2-x-2 / x+2
-2 | 1 2 -1 -2
-2 0 2
_________
1 0 -1 0
This means x^2-1 with no remainder, but we can still break it down. The factors of -1 are 1 and -1, so we must find the factors:
1 | 1 0 -1
1 1
______
1 1 0
This means x+1 so that's one factor
-1 | 1 0 -1
-1 1
_______
1 -1 0
This means x-1 so that's the other factor
Thus, the factors of x^3+2x^2-x-2 are (x+2)(x+1)(x-1)
