Answer:

The answer is 28.

Step-by-step explanation:

Ok.

☆7x and 3x + 16 are congruent, meaning they equal the same.

☆Since they are equal, we can make an equation out of then.

7x = 3x + 16

☆Then we just solve.

$\: \: \: \: \: \: \: \: \: 7x = 3x + 16 \\ \frac{- 3x = - 3x}{4x = 16} \\ \\ \frac{4x}{4} = \frac{16}{4} \\ \\ x = 4$

☆Therefore, x equals 4.

☆We are solving for m<KJL so all we need to do is plug in.

$7x \\ 7(4) \\ 28$

☆You answer is 28.

Answer:

Area = 64π

Area \: = \pi {r}^{2}Area=πr

64 \: \pi \: = \pi {r}^{2}64π=πr

{r}^{2} = \dfrac{64\pi}{\pi}r

64π

{r}^{2} = 64r

=64

r \: = \: \sqrt{64} = 8r=

Radius = 8 units

Finding the Diameter -

Diameter = Radius x 2 = 8 x 2 = 16 .

How is a rectangle similar to a square?

STatiana [176]

Answer:

So a square is a special kind of rectangle, it is one where all the sides have the same length. Thus every square is a rectangle because it is a quadrilateral with all four angles right angles. However not every rectangle is a square, to be a square its sides must have the same length.

Hope this helps!
