To get rid of the parantheses we must multiply -4 times anything inside the parantheses.

-4(7x+5)=-160

-28x-20=-160

Add 20 to both sides of the equation.

-28x-20=-160

-28x=-140

Divide both sides by -28

-28x/-28=-140/-28

x=5

Our final answer is 5

Hope this helps!

Answer:

Step-by-step explanation:

a) Let's $x$ the length of the side of the small square.

Thus,

$x^{2} + (\sqrt{40})^2 = (\sqrt{50})^2$

$x^{2} + 40 = 50$

$x^{2} = 50 - 40$

$x^{2} = 10$

$x = \sqrt{10}$

$x=3.16$

b) Now, the area of the small square is

$A= x^{2}$

$A=(3.16)^2$

$A=9.99$
