Answer:
1. X^2+1/2x = 
2. X^2+2x-3 = 
3. (2x-3)^2 = (2x-3)(2x-3)
4. X^3+2x^2-19x-20 = 
Step-by-step explanation:
Each expression can be written as a product of linear factors as follows
1. X^2+1/2x ⇒ 
=
Hence, X^2+1/2x =
2. X^2+2x-3 ⇒ 
Hence, X^2+2x-3 =
3. (2x-3)^2 ⇒
Hence, (2x-3)^2 = (2x-3)(2x-3)
4. X^3+2x^2-19x-20 ⇒ 
First,
∴ 
Hence, X^3+2x^2-19x-20 =
Answer:
1.5
Step-by-step explanation:
Answer:
5 cm
Step-by-step explanation:
the perimeter of a square with sides of 9 cm is 36 cm so the rectangle must have the same perimeter
if the length of the rectangle is 13cm, its opposite side is also 13cm
add 13 + 13 to get 26
let 'n' = width of rectangle
perimeter = 26 + n + n
36 = 26 + 2n
2n = 10
n = 5
Answer:
replace x with each of the value then solve for the value
Step-by-step explanation:
when raised to the power of a negative you do the inverse
2^-2 = 2^1/2
