Answer:

149 ft^2

Step-by-step explanation:

First, figure out the whole square area.

Which is 9 1/4 x 20 = 185

One triangle is 6 x 6 x .5 because the formula of a triangle is A=bh1/2.

Triangle=18

There are two triangles so its 36.

185-36 = 149

Is this helpful? Tell me if you need me to further explain.

Take second equation here, 
2x + 9 = -12
2x = -12 - 9
2x = -21
Multiply by 2, 
4x = -42

Now, substitute the vaue of 4x in 1st equation, 
-42 - y = 2
-y = 2 + 42
y = -44

In short, Your Answer would be -44

Hope this helps!

Find an equation of the line that (a) has the same y -intercept as the line y + 5x + 9 = 0 and (b) is parallel to the line - 3x
kap26 [50]

Equation of required line is:

y = \frac{3}{4}x-9

Step-by-step explanation:

First of all we will convert both equations in slope-intercept form

y + 5x + 9 = 0

Subtracting 5x from both sides

y+9 = 0-5x\\y+9 = -5x

Subtracting 9 from both sides

y+9-9 = -5x-9\\y = -5x-9

The y-intercept is -9.

Other equation is:

- 3x + 4y = 3

Adding 3x on both sides

-3x+3x+4y = 3x+3\\4y=3x+3

Dividing both sides by 4

\frac{4y}{4} = \frac{3x+3}{4}\\y = \frac{3}{4}x+\frac{3}{4}

As the required line has y-ntercept of line y + 5x + 9 = 0

So,

b = -9

And

The line is parallel to second line, so the slopes of both will be equal

m=\frac{3}{4}

Slope-intercept form of line is:

y=mx+b

Putting values of b and m

y = \frac{3}{4}x-9

An angle measures 86° more than the measure of its supplementary angle. What is the measure of each angle?
Harlamova29_29 [7]

Let the angke be x

Its supplementary angle = 180 - x

Given:

x = 180 - x + 86

2x = 266

x = 133⁰

The one angle = 133⁰

The other angle = 180⁰ - 133⁰ = 47⁰
