Step-by-step explanation:
A rule is that if there is a negative sign before the parenthesis and in the parenthesis next to each other, you make it a addition sign. So it would be 4+1. Which is 5.

<span>Ratio!
Two different numbers are considered proportional if they have the same ratio.
Let’s have an example:
=> I the price of an apple is 2 dollars,
=> then the price of 10 apples are 20 dollar
=> the price of 100 apples are 200 dollars
=> the price of 150 apples are 300 dollars.
And so on…. As long as their values are related, they are proportional.
another example:
=> my hair grows 5 inches in 1 month
=> it grows 10 inches in 2 months</span>
Answer:
25 degrees
Step-by-step explanation:
The sum of the 80 and 55 degree angles and the unknown angle x must be 180 degrees. Thus, x + 80 + 55 = 180, or x + 155 = 180, or x = 25.
x is 25 degrees.
This is based upon the "corresponding angles" principle. Lines AB and CD are parallel and are intersected by the longer diagonal line if we extend this line past the 80 and 55 degree angles.
