Answer:

Irregular polygons are polygons that do not have equal sides or equal angles. When finding the area of an irregular polygon, partition the polygon into smaller regular polygon shapes. You can then plug those measurements into their respective area formulas and multiply to find the area of one part of the shape.

This is 16cm.

4a - 5 + 2a + 9 = 28
BaLLatris [955]

Answer:a=4

Step-by-step explanation:

Simplifying

4a + -5 + 2a + 9 = 28

Reorder the terms:

-5 + 9 + 4a + 2a = 28

Combine like terms: -5 + 9 = 4

4 + 4a + 2a = 28

Combine like terms: 4a + 2a = 6a

4 + 6a = 28

Solving

4 + 6a = 28

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-4' to each side of the equation.

4 + -4 + 6a = 28 + -4

Combine like terms: 4 + -4 = 0

0 + 6a = 28 + -4

6a = 28 + -4

Combine like terms: 28 + -4 = 24

6a = 24

Divide each side by '6'.

a = 4

Simplifying

a = 4

When 8 is subtracted from a certain number and the result is multiplied by 3 the answer is 21. What is the original number?​
Debora [2.8K]
The original number is 15.

Let’s work it out.

First, divide.

21 divided by 3 is 7.

Now, add.

8 + 7 = 15

This is true because...

15 - 8 = 7



Hope this helps, have a great day, stay safe and positive.
