(5x + 2) + (4x + 5)​

Mathematics
1 answer:
Dmitrij [34]3 years ago
6 0

Answer:

9x+7

Step-by-step explanation:

This is because you combine like terms:

5x and 4x contain the same variable and amount of variables so you can combine them making 9x. You are then left with two numbers 5, and 2 they aren't attached to any variables and are in common in that way so you combine them too! This makes them 7, lastly you make it into an expression so you can't combine 9x and 7 so you leave it as 9x+7!!!

What is the measure of arc BD?
posledela
Since there is no specific situation or measurements for this, we just assume a circle with an arc BD. It has arbitrary values. In a circle, an arc can be measured by the measure of an arc. A measure of an arc is an angle that an arc makes at the center of a circle which it is a part.  It has degrees units. It can be calculated when the length of an arc is given by using certain equations. The measure of an arc and the length of an arc always goes together.
