Question

Can someone help me please

Answer 1

Answer:

$6x^2+8x$

Step-by-step explanation:

Hey there!

In order to find the answer to this question, what you need to do is first find the area of the whole grey box as a whole (including the white box to)

The dimensions for this is 3x+2 and 4x

Now we know that to find area, we need to multiply length by height

So (3x+2)(4x) is what we have to solve to get the area

Now we simplify:

1. Distribute

2. $12x^2+8x$

So now we know that the total area is $12x^2+8x$

Now what we do is take out the area of the white box from the area of the grey box

Lets find the area of the white box:

l=3x   (l - length)

h=2x (h - height)

$3x*2x=6x^2$

Now we have the area of both shapes

Since we have all the information we need to find the final answer, the following steps below will be using the information we found to find the final answer:

In order to find the final answer which is the area of the shaded region, we take out the area of the white region from the total area of the grey region (including the white region)

So now we can formulate this new equation:

$12x^2+8x-6x^2= ta$

(ta= total area)

Now we simplify:

$6x^2+8x$ is going to be our final answer

So our final answer is $6x^2+8x$
