AC side and BC side have the same length because ΔCDA and ΔCDE are congruent.
The equation will be
AC = BC
Solve the equation
AC = BC
2x = 3x - 10
2x - 3x = -10
-x = -10
x = 10
The value of x is 10
The box was filled with exactly 125 unit cubes because volume means it has to be filled.

First we need to write the factors of the polynomial. In order for 1, 4, and -3 to be roots, they need to be the x values that make the polynomial equal 0.
(x - 1) = 0
That would be the factor for x = 1 because when we plug 1 in for x we get 1 - 1 which equals 0.
Multiply all the factors together.
(x-1)(x-4)(x+3)=0
Now FOIL.
![(x^2-5x+4)(x+3)](https://tex.z-dn.net/?f=%28x%5E2-5x%2B4%29%28x%2B3%29)
Answer:
Yes
Step-by-step explanation:
If you distribute 7(x + 10), you get 7x + 70.
There are 3 odd numbers in the set {1,2,3,4,5}
So P(ODD) = 3/5
Your question is what is the expectation of getting an odd number in 240 spins:
240 x 3/5 = 144 number of Odds
