Answer: -29a-6b+59c
You need to combine like terms

3 0

Answer:

-29a - 6b + 59c

Step-by-step explanation:

First, keep in mind that only like terms can be combined.

5a + 7b - 12a + 6c - 13b - 22a + 53c

You can rearrange them to make it easier:

<u>5a - 12a - 22a</u> + <u>7b - 13b</u> + <u>6c + 53c</u>

<u>-29a</u> <u>- 6b</u> + <u>59c</u>

Quadrilateral CAMP below is a rhombus. The length of PQ is (x + 2) units, and the length of QA is
Phoenix [80]

Q cuts the diagonal PA into 2 equal halves, since the diagonals of rhombus meet at right angles.

<u>Step-by-step explanation:</u>

As given by the statement in the problem,

Q may be the middle point, which cut the diagonal PA into 2 equal halves.

In rhombus, diagonals meet at right angles.

which means that PQ = QA

x+2 = 3x - 14

Grouping the terms, we will get,

3x -x = 14+ 2

2x = 16

dividing by 2 on both sides, we will get,

x = 16/2 = 8

8+2 = 3(8) - 14 = 10 = PQ or QA
