12m-6-2m+10 (10m+4) is the simplest it can go
saw5 [17]4 years ago

Answer:

10m - 16

Step-by-step explanation:

3 (4m-2) -2(m+5)

The equivalent expression can be simplified as an expression with two terms as follows:

3 (4m-2) -2(m+5)

Open each parenthesis by multiplying the outside value with the values in the parenthesis.

3 (4m-2) = 12m - 6

-2(m + 5) = -2m -10

Bring the value together

12m - 6 -2m  - 10

collecting like terms

12m -2m - 6 - 10

10m - 16

Will GIVE BRAINLIEST IF CORRECT<br> The diagram shows a convex polygon.<br> Find the value of a.
katen-ka-za [31]

Answer:

The value of a is 15.

Step-by-step explanation:

First, you have to find the total interior angles of the polygon using the formula, sum = (n-2)×180°, where n represents the number of sides :

sum = (n-2)×180°

sum = (5-2)×180°

sum = 540°

Given that the sum of the interior angle is 540° so in order to find the value of a, you have to add up all the angles in terms of a :

3a + 150 + 8a + 6a + 9a = 540

26a + 150 = 540

26a = 390

a = 390 ÷ 26

a = 15
