Answer:

Step-by-step explanation:

Here's the complete question:

Write the word sentence as an equation. Then solve the equation. A number k increased by 7 is 34.

An increase in k simply means that there's an addition. This will be:

k + 7 = 34

k = 34 - 7

k = 27

Therefore, the value of k is 27

PLEASE HELP!!! I WILL GIVE BRAINY!!!

The first one is 4/3

We can solve by,

${x}^{2} \times 180 = 320$

$x = \frac{4}{3}$

${ \frac{4}{3} }^{2} \times 180 = 320 = true$

~~

The second one is 35.

Idk how to explain...

~~

The third one is a 6 - gon therefore cannot be C or D.

I'd say the third one is A., it looks like it's caving in.
