Answer:

x = 40

Step-by-step explanation:

The sum of the angles of a triangle add to 180 degrees

x+2x+x+20 = 180

Combine like terms

4x+20 =180

Subtract 20 from each side

4x+20-20 =180-20

4x = 160

Divide each side by 4

4x/4 =160/4

x = 40

15 - t + 8t = -13 <br> 4a + 11 - a = 2
Step2247 [10]
15-t + 8t = -13
15 + 7t = -13
7t = -13-15
7t = -28
t = -4

4a + 11-a = 2
3a = 2-11
3a = -9
a = -3

Answer:

Slope = -5/8

Step-by-step explanation:

Take 2 points from the graph where the line is. Point 1: (1 , 6). Point 2: (9 , 1).

We are going to use the formula for finding the slope of a line now.

y2 - y1/x2 - x1 = 1 - 6/9 - 1 = -5/8

Slope = -5/8

How would I do this plz help

Answer:

273 m^2

Step-by-step explanation:

Firstly, you should find the area of the triangle. Remember that the formula for a triangle's area is (Base x Height) ÷ 2

Therefore,

11 x 14 is 154

154/2 = 77 m^2

Then, we find the area of the square which is just Base x Heigh

14 x 14 is 196m^2

And finally, we just add the two

77 + 196 = 273 m^2

The reason it's not m^3 is because we're not dealing with a third dimensional figure.

Btw, ^ means to the power of.
