Answer:
Step-by-step explanation:
- 2x²c² + 3xc² - 35c² =
- c²(2x² + 3x - 35) =
- c²(2x² + 10x - 7x - 35) =
- c²(2x(x + 5) - 7(x + 5)) =
- c²(x + 5)(2x - 7)
Hello,
if 2x²=54 then (2x)²=4x²=2*2x=2*54=108
Answer:
Part 1. 10 modules per floor
Part 2. Two different rectangular prism
Step-by-step explanation:
Let
x ----> the number of modules
y ---> the number of stories
we have
x=150\ modules\\y=15\ stories
Divide the number of modules by the number of stories
so
\frac{x}{y}=\frac{150}{15}=10\ \frac{modules}{floor}
Answer:
3
Step-by-step explanation:
Given the expression a --b
Given that
a = 2
b = 1
Substitute into the expression
a--b
= 2 --1
= 2 - (-1)
= 2 + 1
= 3
Hence the required value is 3
Answer:
Given:
n = 15
