1) Find the missing side.
kari74 [83]

Answer:

25inch

Step-by-step explanation:

Ok so there is something called a Pythagorean theorem.

It's a²+b²=c²

It works on right triangles

C is the longest side or the side not touching the right angle

and a and b is the other 2 sides

so the missing side is 24²+7²=Missing side or c²

24²=576 and 7²= 49  

576+49=625

\sqrt{625}=25

Refer to the rectangle below. The length of the rectangle is x + 12. The width of the rectangle is x + 3.
Elis [28]

Answer:

x^2+15x+36

Step-by-step explanation:

The complete question is shown in the attachment.

The length of the rectangle is x + 12. The width of the rectangle is x + 3.

Recall that area of a rectangle is Length \times Width

In terms of x, the area is (x+12)(x+3)

Recall the distributive property of real numbers: (a+b)(c+d)=a(c+d)+b(c+d)

We apply this property to get:

(x+12)(x+3)=x(x+3)+12(x+3)

We expand again to get:

(x+12)(x+3)=x^2+3x+12x+36

We now simplify to obtain:

(x+12)(x+3)=x^2+15x+36

The area of the rectangle is x^2+15x+36
