Answer:
12x^2-4x
Step-by-step explanation:
5x + 4x^2 - 9x + 8x^2
Combine like terms
4x^2+8x^2+5x-9x
12x^2-4x
Answer:
id say b
Step-by-step explanation:
but i mean idk really
Answer:
no error was made
Step-by-step explanation:
5x- 1/5*(20x +5) =9
distribute
5x - 4x-1 = 9
combine like terms
x-1 =9
add 1 to each side
x-1+1 = 9+1
simplify
x = 10
Answer:
part A. area = L X H
9 x 8/9 = 72/9 = 8 square feet
Part B. Draw a line diagonally either between Point A & C or B & D, this would make 2 triangles.
the area of the triangle would be half of the full area so 8 / 2 = 4 feet square
Step-by-step explanation:
So basically, all we have to do is change the signs when we multiply or divide by a negative so our answer is "When dividing by -8, she did not change the signs.
