Answer:

115.2 in²

Step-by-step explanation:

Area of two triangles =

4 x 3 = 12

Area top rectangle/parallelogram =

5 x 8.6 = 43

Area back rectangle =

3 x 8.6 = 25.8

Area bottom rectangle =

4 x 8.6 = 34.4

Total = Sum of all areas

115.2 in²

If my answer is incorrect, pls correct me!

Answer:

109.2

Step-by-step explanation:

triangles=3x4/2=6

smaller rectangle=8.6x3=25.8

medium rectangle=8.6x5=43

large rectangle=8.6x4=34.4

6+25.8+43+34.4=109.2

Step-by-step explanation:

Answer:

Circumference formula:

π is the constant and π = 3.14

Círclє Díαmєtєr Círcumfєrєncє

( A ). 3 cm 9.42 cm

( B ). 10 cm 31.40 cm

( C ). 7.64 cm 24 cm

( D ). 5.73 cm 18 cm

( E ). 1 cm 3.14 cm.

◈ Circumference of circle = π × diameter

◈ Diameter of circle = Circumference of circle / π

usíng vαluє σf π = 3.14

( A ) Díαmєtєr = 3 cm

Círcumfєrєncє = 3.14 × 3 = 9.42 cm.

( B ) Díαmєtєr = 10 cm

Círcumfєrєncє = 3.14 × 10 cm = 31.40 cm.

( C ) Círcumfєrєncє = 24 cm

Díαmєtєr = 24 / 3.14 cm = 7.64 cm.

( D ) Círcumfєrєncє = 18 cm

Díαmєtєr = 18 /3.14 = 5.73 cm.

( E ) Díαmєtєr = 1 cm

Círcumfєrєncє = 3.14 × 1 cm = 3.14 cm.

Answer:

∠5

Step-by-step explanation:

A linear pair of angles create a straight line

The only angle that creates a straight line with ∠1 is ∠5 therefore cyan is the answer

Answer:

5 i think

Step-by-step explanation:

The measure of a straight angle is 180 degrees so a linear pair of angles must add up to 180 degrees

Answer:

2x^2

Step-by-step explanation:

I would just multiply the x by 2 before adding the exponent

Answer:

Y=3x+5

Y=½x-2

Step-by-step explanation:

already already answered

Answer:

Step-by-step explanation:

sir in the graph every point is (X,Y) so you should choose consecutive random numbers for the X values for the first point after that put the values you choose In the equations so now you have just numbers in the equation .. add, subtract and multiply at the end you will get a value .. ok this Y for the first point .. mark this point on the graph and continued this process until it reached at least 3 points, and connected between them.

Note : do this with each equation separately and do not connecte between two points for two different equations

the equation with x will become as line

the equation with x² will become as arch

after you finsh drwaing see the points that the tow equation are touching within and write them. Usually it is two points

Step-by-step explanation:

First, set the equations as equal to eachother because both equal y:

[tex]x^2-6x-7=x+1[/tex]

Now, solve to get everything on one side of the equation so that the other side of the equation is set to 0:

[tex]x^2-7x-8=0[/tex]

Now use the sum product pattern:

[tex]x^2+x-8x-8[/tex]

(as you can see, the above equation is equivalent to the previous equation, but there are now four values instead of three)

Now take the common factor from the two pairs:

[tex]x(x+1)-8(x+1)[/tex]

Rewrite in factored form:

[tex](x-8)(x+1)[/tex]

Now to get both values of x, set each factored equation to 0 and solve for x (becuase remember, the equation still equals 0):

[tex](x-8)=0\\x=8[/tex]

[tex](x+1)=0\\x=-1[/tex]

NOW that we have both values of x, we can subsitute them into EITHER equation and solve to get the corresponding y values:

[tex]y=(8)+1\\y=9[/tex]

[tex]y=(-1)+1\\y=0[/tex]

So that's how we solve to get these coordinates: (8,9) & (-1,0).

Good luck on your final and I hope I was able to help :)

The red line is the entire angle which is shown as 66.8 degrees.

One of the two angles is shown as 40.8 and the other one is x.

To find x subtract 40.8 from 66.8

X = 66.8-40.8 = 26

X = 26 degrees.
