5 0

Answer:

Step-by-step explanation:

It is an obtuse triangle because one angle (5) takes up more than the sum of the other two (3+1=4).

The angles are:

5+3+1 = 9

Each angles is

5/9 * 180 = 100°

3/9 * 180 = 60°

1/9 * 180 = 20°

Total = 100+60+20 = 180 degrees.

Ifp * (x) = 3x ^ 2 - 4 and r(x) = 2x ^ 2 - 5x + 1 . find value r(x + 2)

valina [46]

Answer:

Step-by-step explanation:

$r(x) = 2x ^ 2 - 5x +1\\\\ r(x+2) = 2(x+2)^ 2 - 5(x+2) +1\\\\ r(x+2) = 2(x^2+4x+4) - 5x-10+1\\\\ r(x+2) = 2x^2+8x+8 - 5x-9\\\\ r(x+2) = 2x^2+3x-1$

Given the area of a square is 225 square feet, what is the length of each side

alexdok [17]

The area of a square can be found by squaring one side.

Let's set the side as x feet.

x^2=225
x=square root of 225
x=15

The length of each side is 15 feet.

Hope this helps!
