Answer:

10x-8=b

--------(over)

ax

Step-by-step explanation:

2 (5x-4) = ax +b

distrbute 2

10x-8=ax+b

divide each side by ax

Find the product (x+2)(x+3)

Katyanochek1 [597]

Answer:

$x^{2}$ +5x+6.

Step-by-step explanation:

Here you can use the foil method.

1. Multiply x by x to get $x^{2}$ .

2. Multiply x by 3 to get 3x.

3. Multiply 2 by x to get 2x.

4. Multiply 2 by 3 to get 6.

Now, you have to add all those terms to get $x^{2}$ +3x+2x+6 and you can simplify that to $x^{2}$ +5x+6.

Match the width with the go given area.

LekaFEV [45]

Hello!

<h2>Answer:</h2>

$\boxed{ \bf 1.~l~=~9.25~cm;~A~=~55.5~cm^2~matches~with~the~last~option~w~=~6~cm.}$

$\boxed{ \bf 2.~l~=~7.5~cm;~A~=~48.75~cm^2~matches~with~the~second~option~w~=~6.5~cm.}$

$\boxed{ \bf 3.~l~=~5~cm;~A~=~44~cm^2~matches~with~the~third~option~w~=~8.8~cm.}$

$\boxed{ \bf 4.~l~=~5~cm;~A~=~31.25~cm^2~matches~with~the~first~option~w~=~6.25~cm.}$

<h2>__________________________________</h2><h2>Explanation:</h2>

We already know that the formula for area of a rectangle is A = l × w.

Notice how the width and the length are being multiplied to find the area.

Well, to find the width, we must do the <em>opposite</em> of multiplication, which is division.

Since we already have the length, all we have to do is divide the area by the length for each of the questions.

1:

A = l × w

55.5 = 9.25 × w

$\frac{55.5}{9.25}$ = 6

2:

A = l × w

48.75 = 7.5 × w

$\frac{48.75}{7.5}$ = 6.5

3:

A = l × w

44 = 5 × w

$\frac{44}{5}$ = 8.8

4:

A = l × w

31.25 = 5 × w

$\frac{31.25}{5}$ = 6.25
