A). add 9 to both sides.

This is will get x by itself.

x - 9 = 0

x - 9 + 9 = 0 + 9

x = 9

In your computation, approximate its value as 3.14.

Answer: d

Step-by-step explanation:

Find the area of the rectangle.

$A=l*w\\A=(15in)(12in)\\A=180in^2$

Find the area of the base of the semicircle.

$A=\pi r^2$

12 in would be the diameter, divide by 2 to get the radius.

$\frac{12}{2}=6$

Plug this into the formula.

$A=(3.14)(6)^2\\A=113.04in^2$

Since we do not have a full circle but a semi one instead, we must divide our result by 2.

$\frac{113.04}{2}=56.52in^2$

Add both areas.

180+56.52=236.52 $in^2$

8=1/3(a+5)<br><br> Please help and thank you :)

Answer:

a=19

Step-by-step explanation:

First we have to distribute the parenthesis; multiply (a+5) by 1/3

8=1/3*a+1/3*5

Now we just solve the equation regularly

8=1/3a+5/3

8-5/3=1/3a

6 1/3=1/3a

a=19

Answer:

(0,-5) and (-4,3)

Step-by-step explanation:

The given equations are

$\left \{ {{x^2+y^2=25} \atop {2x+y=-5}} \right.$

Make y the subject in the second equation;

$y=-2x-5$

Substitute into the first equation;

$x^2+(-2x-5)^2=25$

Expand:

$x^2+4x^2+20x+25=25$

$x^2+4x^2+20x+25-25=0$

$5x^2+20x=0$

$5x(x+4)=0$

$\Rightarrow x=0,x=-4$

When x=0,

$y=-2(0)-5=-5$

This gives; (0,-5)

When x=-4

$y=-2(-4)-5=3$

This gives (-4,3)
