It’s B
You need to use the Pythagorean theorem which is a squared + b squared = c squared
So a^2+4^2=5^2
Simplified that would be a^2 + 16 = 25
Subtract 16 from both sides
A^2=9
And the square root of nine is 3
I think it's the last one because strong and hold together atoms and weak nf break them, showing a relationship
Solve the rational equation by combining expressions and isolating the variable.
q = 2
Sales tax is an additional amount of money you pay based on a percentage of the selling price of goods and services that are purchased. For example, if you purchase a new television for $400 and live in an area where the sales tax is 7%, you would pay $28 in sales tax. Your total bill would be $428.88
