Answer: - 4d
Step-by-step explanation:
In the equation, there's an invisible 1 in front of the first d, so let's add that.
1d - 2d - 3d
Since all the terms in the above equations are like terms, we would focus on only subtracting. We would first subtract 2d from 1d.
- 1d - 3d
We then subtract 3d from - 1d. This would give us our answer.

that is :

The measures of the exterior angles of a heptagon are x°, 2x°, 3x°, 5x°, 7x°, 8x°, and 10x°. Solve for x.
Answers
Answer:
x = 10
Step-by-step explanation:
Exterior angles in any polygon always measure 360°
x + 2x + 3x + 5x + 7x + 8x + 10x = 360°
36x = 360
x = 360/36
x = 10

The length of the model is 6 inches.
Step-by-step explanation:
The wingspan of the airplane and length of the airplane are a ratio of 4:3
The model is also supposed to be 4:3.
4:3 x 2 = 8:6
Or, 20x12=240
240/8=30

Step-by-step explanation:
3x + 6 + 2x + 14 = 180
5x + 20 = 180

Find the measure of the indicated angles.show work.complete sentence a. m<QRP = ____
b. m<QRX = ____
Answers
The measure of m<QRX and m<QRP are 129 and 51 degrees respectively.
The sum of the interior angle of a triangle is 180 degrees, hence;
m<QPR + m<QRP + M<PQR = 180
Substitute the given parameters
49 + m<QRP + 80 = 180
m<QRP + 129 = 180
m<QRP = 180 - 129
m<QRP = 51 degrees
The sum of interior angle is equal to the exterior
m<QPR + M<PQR = m<QRX
m<QRX = 49 + 80
m<QRX = 129 degrees
Hence the measure of m<QRX and m<QRP are 129 and 51 degrees respectively.
