I think you would just have to find the square roots

exis [7]

Answer:

Q1. -45

Q2. -10

Q3. 31?

Step-by-step explanation:

Q1 -- you times -8 and 2 which comes out to -16. Since you have -16 + 1 inside of the parentheses you add 1 to -16 which comes out to -15. Then you take -15 times 3 and it comes out to -45.

Q2 -- the m gets replaced by the 5 so now its -2 times 5. Which comes out to -10. Then you take -10 times 2, which is -20. Now take -20 + 10 which gives us the answer of -10.

Q3 -- I'm not completely sure on this one but I think the equation would transfer to this 2*5 + 5*3 + 2*3. So 2*5 is 10, 5*3 is 15, and 2*3 is 6. Add them all together and you get 31.

I hope this was right and it helps you!

Shanell answered al of her answer on her science test she had 90% correct there were 40 questions how many did she get incorrect
Snowcat [4.5K]

Answer:

4

Step-by-step explanation:

If she got a 90% on her test, and the test was 40 questions long, we need to do a bit of division and multiplication.

We have to divide 40 by 100, as percentages are out of 100.

So now we have 0.4.

Now we multiply this by 90.

36. She got 36 answers correct out of 40, which means she got four wrong.
