Here’s the answer:
(It didnt let me send the response so I took a screenshot)
To figure out one measure of a triangle, we use A2+B2=C2
(Where a is the first measure times itself, b is the second side times itself and c is the longest side times itself). Once you figure that out and plug all your numbers into the formula, you can solve like a regular equation. 45 times 45 is 2,025. 85 times 85 is 7,225. We don't know c so we just put that as C2. Our equation- 2,025+7,225= C2
Add the numbers to get 9,250= C2
Our answer is 96. (Because 96 times itself is 9,250). The answer is not exact so I just rounded it to the nearest whole number.
Answer:
y = -6, x =2
Step-by-step explanation:
To solve by elimination, you have to line both equations up together. Then, you multiply both equations until one variable is removed.
2x+y = -2
5x + 3y = - 8
There are many different ways to solve an elimination problem, but generally you should look for the simplest route. Here, I would multiply the top equation by -3.
-6x -3y = 6
5x +3y = -8
Imagine you are adding the two equations together. You end up with
-x = -2
Then solve for x. In this situation, it is fairly simple. Take out a factor of -1.
x = 2
Finally, choose one of your beginning equations and plug your new-found x value back into the equation.
2(2) +y = -2
4 + y = -2
y = -6
So that gives you
4×5^2-5×3^2
First you have to do the exponents
5^2=25
3^2=9
Now you have 4×25-5×9
4×25=100
5×9=45
100-45=55
55 is the answer.
