Answer:

5x + 17

Step-by-step explanation:

To answer this question, we must first simplify:

2 (x + 7) + 3 (x + 1) = 2x + 14 + 3x + 3

Then, we have to combine like terms:

2x + 14 + 3x + 3 = 5x + 17

And there is our answer, 5x + 17

Hope this helps ! :)

Using this formula l=A 1/2 what is the length of one side of a square with an area of 1,936 square kilometers? (A is the area of

Vera_Pavlovna [14]

c.)44 kilometers

Answer:

Solution given:

let

length =L

and

Area =A

Now

we have

Area [A]=1936 square kilometers

now

As we know that

Area of square :length *length

A=l*l

A=l²

Substituting value of A

1936=l²

doing square root on both side

$\sqrt{1936}=\sqrt{l²}$

we get

l= $\sqrt{2*2*2*2*11*11}$

l=2*2*11

l=44 kilometers

the length of one side of a square is 44 kilometers.
