So first you would multiply 17 times 14 and you would get $238

Next, you would multiply 6 times 2, and you would get $12

Finally, you add $12 and $238 and your answer is $250

Which set of transformations would prove ΔLMN ~ ΔPQR?
weeeeeb [17]

Answer:

dilation

Step-by-step explanation:

Well, you didn't give an option to choose from. I know that the thing in the middle is a similar symbol. Dilations can prove that both shapes are similar. If LMN dilates to a smaller shape PQR then both shapes are SIMILLAR.

the length of a rectangle is 4 more than the width. if the perimeter of the rectangle is 57.2 inches find the length and the wid
dusya [7]

Answer:

Length = 16.3 in and Width = 12.3 in

Step-by-step explanation:

Let's name L the length and W the width of the rectangle. We can then write equations describing the statements given:

"<em>the length of a rectangle is 4 more than the width</em>"

L = W + 4

"<em>the perimeter of the rectangle is 57.2 inches</em>"

2 L + 2 W = 57.2

(where we used the formula for the perimeter of the rectangle equal to twice the rectangle's length plus twice the rectangle's width)

Now we use the first equation to substitute for L in the second one:

2 ( W + 4) + 2 W = 57.2

use distributive property to remove parenthesis

2 W + 8 + 2 W = 57.2

combine like terms

4 W + 8 = 57.2

subtract 8 from both sides

4 W = 57.2 - 8 = 49.2

divide both sides by 4 to isolate W

W = 49.2 / 4 = 12.3 in

Now we use this result in the first equation we wrote, to find L

L = W + 4 = 12.3 + 4 = 16.3 in

Therefore : Length = 16.3 in and Width = 12.3 in
