What is 2/3(3x+9)=−2(2x+6)

dimulka [17.4K]

Answer:

Area = 5x^2 +7x -26

Step-by-step explanation:

The area of the shaded region can be found if you substruct the small rectangle from the big one. The area of any rectangle is calculated if you multiply width and height.

In other words:

A_small = (x-3)(x-6) = x^2-9x +18

A_big = (2x+2)(3x-4) = 6x^2 -2x -8

A_big - A_small = (6x^2 -2x -8) - (x^2-9x +18)

= 6x^2 -2x -8 - x^2 + 9x -18

= 5x^2 +7x -26

Find the greatest common factor. бах2 + бах + ба

ad-work [718]

Answer:

6a

Step-by-step explanation:

The GCF (Greatest Common Factor) is a number/variable that you can take out of all of the terms in the expression.

In this case, each term in this expression has a 6, and an a, but not all have an x, so we only take out:

6a

By taking 6a, you get:

6a( $x^2$ + x + 1)

Can someone explain how these equal 5 and -5 please

uysha [10]

I'm not sure how you obtained -5 as your answer but this is the mathematical explanation. hope this helps!
${x}^{2} + 3x = 40 \\ {x}^{2} + 3x - 40 = 0 \\(x + 8)(x - 5) = 0 \\ x = - 8 \\ x = 5$
