Answer:

D. N = w² + 8w + 12

Step-by-step explanation:

The current size is w by w+4, so the area is ...

A = w(w+4)

When each dimension is increased by 2, the new size is (w+2) by (w+4+2). The latter dimension can be simplified to (w+6). Now, the new area is ...

N = (w+2)(w+6) = w² +8w +12 . . . . . . . matches choice D

Kit bought a soft drink and a sandwich for $9.00. What was the price of each if the sandwich cost 3.5 times much as the soft dri

astra-53 [7]

Let the cost of the soft drink = C then the price of the sandwich was 3.5 times as much = 3.5C

And

C + 3.5C = Total Cost

C + 3.5C = 9

4.5C = 9 divide both sides by 4.5

C = 9/4.5 = $2.00 for the soft drink

And 3.5C = 3.5(2.00) = $7.00 cost of the sandwich

ADHE - ADGF below. Find the value of 'x'. X H н E 8 2. 12

Vlad1618 [11]

Given:

$\Delta DHE\sim \Delta DGF$

To find:

The value of x.

Solution:

We know that, corresponding sides of similar triangles are proportional.

Since, $\Delta DHE\sim \Delta DGF$ , therefore

$\dfrac{HE}{GF}=\dfrac{DE}{DF}$

On substituting the values from the figure, we get

$\dfrac{8}{12}=\dfrac{x}{x+2}$

$\dfrac{2}{3}=\dfrac{x}{x+2}$

On cross multiplication, we get

$2(x+2)=3x$

$2x+4=3x$

$4=3x-2x$

$4=x$

Therefore, the value of x is 4.
