Monica [59]

The correct answer is:

D. ∠FGE≅∠NMP

Explanation:

The symmetric property states that if two quantities are equal (or congruent), you can "flip" them around the equals sign (or congruence sign).

This means since EFG is congruent to HJK, then HJK is congruent to EFG.

A rectangle has a length of 3x + 7 and a width of 2x. If the perimeter of the

Art [367]

Answer:

The length of the rectangle is 31.

Step-by-step explanation:

We have that the length (L) and width (W) are:

$L = 3x + 7$

$W = 2x$

The perimeter of the rectangle is given by:

$P = 2W + 2L$

$94 = 2(2x + 3x + 7)$

$94 = 10x + 14$

$x = 8$

Now, we can calculate the length of the rectangle:

$L = 3x + 7 = 3*8 + 7 = 31$

Therefore, the length of the rectangle is 31 units.

I hope it helps you!

Lauren is sewing a quilt using fabric squares.

KengaRu [80]

Answer:

x^2 + 8x + 16

Step-by-step explanation:

Given length of square x + 4.

Area of square with side S is given by $S^2$ .

Therefore are of square with side x + 4 is given by $(x + 4)^2$

Area of square = $(x + 4)^2\\=>(x + 4)*(x + 4)\\=> x(x + 4) + 4(x + 4)\\=> x^2 + 4x + 4x + 4*4\\=> x^2 + 8x + 16$

Thus, x2 + 8x + 16 expression represents the area of a fabric square.

Step-by-step explanation:

$\int _{2.2}^{+\infty \:}\frac{10.648}{x^2}dx = 10.648 \int _{2.2}^{\infty \:}\frac{dx}{x^2}$

$= - \frac{10.648}{x} | _{2.2}^{ \infty} = 4.84$
