Answer: -8x
Step-by-step explanation: to get the answer you would multiply 4x and -2.
4x*-2= -8x
Hello!
You have already earned 12.25 dollars. So now, you need to earn $31.75. If each errand is $1.50, you can divide $31.75 by $1.50. You would get roughly 21.17. Since you can not do 21 errands and .17 of an errand, you would need to do about 22 errands to get the money you need, which is the $31.75. 1.50 times 22 is equal to thirty-three, so youd be getting about a dollar and 25 cents more than what you need. We can had 33 (what we earn from our 22 errands) to 12.25, which is what we already have, and we get 45.25! So you can earn more money than you need to earn.
Hope this helps, have an awesome day!

Answer:
I believe this is pathgorean theorem, which I did at the beginning of alegbra last year. It is basically finding the missing side of a triangle. (Trust me some of the easiest stuff you do all year) Below are my notes from last year. I hope it helps! Good Luck!!!
Step-by-step explanation:
Given two sides
If you know two other sides of the right triangle, it's the easiest option; all you need to do is apply the Pythagorean theorem:
a² + b² = c²
if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root:
a = √(c² - b²)
if leg b is unknown, then
b = √(c² - a²)
for hypotenuse c missing, the formula is
c = √(a² + b²)
