When you're combining 'like terms', look for all the terms that end with 'ab'.
Then add all the numbers that have 'ab' after them.
Answer:
given in the figure an isosceles right triangle
hence
x = √3
- √3 is a <u>surd</u> it can't be simplified further
Answer:
How does it need solved? By graphing? Substitution?
Step-by-step explanation:
We have 11 as our base value, meaning that we add 11 to something, so we have 11+<something>. To find that something, we want to know how long it takes to go 21.78 miles at 33 miles per hour. To get this, we want to turn miles per hour into minutes per mile and multiply that by 21.78 miles to get our answer. Therefore, we cross them out as shown in the equation to get
