Answer:
1. Perfect Square
2. Perfect Square
3. Conjugate
4. Conjugate
5. Perfect Square
-I am about 98% sure about these answers.
-An example for a perfect square is (5x+3)(5x+3) and an example for a conjugate is (5x+3)(5x-3). The only difference between the two is the symbol for the second pair of parenthesis.

Answer:
x = - 4
Step-by-step explanation:
-3(x+2)=6+2x+8
-3x - 6 = 14 + 2x (-3 * 2 = -6)
-3x -2x = 14 + 6
-5x = 20
x = 20/ -5
x = -4
Hi there!
The formula for the perimeter of a rectangle is P = 2 (l + w).
We can simplify this formula so that we can find the solutions easier.
P = 40
40 = 2 (l + w)
divide both sides by 2
40/2 = l + w
20 = l + w
So the length + width has to equal to 20.
So your answers would be B , C , D.
Hope this helped! :)
