Answer:
1) 10mn - 10×m×n
2)15m - 15×m
10×m×n×+15×m
=10mn+15m
factorize
common number(divisor) = 5
5m(2n+3)
5m*2n=10mn
5m*3=15m
Answer:
The big prism= feet squared
Each individual cube= 216 inches squared
Step-by-step explanation:
The big prism LxWxH
The individual cube = 1 foot/6 (amount of edges made of small cubes) = 2 inches.
IDK how to convert from inches to feet though cause I ain't American. Sorry.
Hope that helped!!! k
Take half of the coefficient of the bx term and square on both sides:
x^2 - 10x + (-10/2)^2 = 46 + (-10/2)^2
x^2 - 10x + (-5)^2 = 46 + (-5)^2
x^2 - 10x + 25 = 46 + 25
x^2 - 10x + 25 = 71
Now factor x^2 - 10x + 25 which will give us (x - 5)^2
(x - 5)^2 = 71 is the answer.
Rewrite as
11+(7x)-x=-21
11+6x=-21
6x=-32
X= -32/6 = -16/3
Check:
11+(-16/3*7)+16/3=
11-112/3+16/3=
11-96/3=
11-32=
-21 it works
So...?= -16/3
