 ASAP need today
aivan3 [116]
The answer would be 
x² + 18x + 81 = 44 + 81

To complete the square, we look at the value of b (the coefficient of x).  We take half of it, then square it; this is the number that gets added to both sides.

18/2 = 9; 9²=81

Therefore we add 81 to both sides.

Solve the following system of equations . Plot the solution to the system on the provided graph
navik [9.2K]

Answer:

(6, -3)

Step-by-step explanation:

I will solve this system using elimination.

[tex]\left \{ {{-x+2y=-12} \atop {2x+3y=3}} \right.[/tex]

I will multiply -x+2y=-12 by 2 so that -x becomes -2x.

2(-x + 2y = -12)

Distribute.

-2x + 4y = -24

Now subtract this from the other equation.

2x + 3y = 3

<u>-2x + 4y = -24</u>

        7y  =  -21

Divide both sides by 7.

y = -3

Now that we have the value of y, plug it into the original equation.

-x + 2(-3) = -12

Simplify.

-x - 6 = -12

Add 6 to both sides.

-x = -6

Divide both sides by -1.

x = 6

(6, -3)

The area of a trampoline is 49 pi sqared. What's the diameter of the trampoline?
Flauer [41]

Answer:

The diameter is 14

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

We know the area is 49 pi

49 pi = pi r^2

Divide each side by pi

49 pi/ pi = pi r^2/pi

49 = r^2

Take the square root of each side

sqrt(49) = sqrt(r^2)

7 =r

We want the diameter

d = 2r

d = 2*7

d = 14
