I think you mean x^2 - 7x + 8
This is a basic factoring problem:
What two numbers multiply to make 8 and add to make -7?
There are no two numbers that work!
Therefore, it is prime
65/5=13-3=10 27-17=10
72/6=12-1=11 54-43=11
88/8=11-2=9 27-18=9
90/3=30-8=22 34-10=24
So, that makes "90 ÷ 3 − 8 _____ 34 − 10" not equal.
Hope this helps! Stay Safe!
I don't know if I did it right but here's my guess. I think you multiply 7 by 20% and that gives you 1.40 as a result. Compared to the other method I used (division), I'm pretty sure I'm right since the other result was 35. Doesn't make sense if the end amount was $7.
Answer: No, the answer is 29, this is false.
Step-by-step explanation: 63-x=34
subtract 63 from both sides
34-63= -29
-x=-29
divide both sides by the negative and you get 29
plug in 29 for x, 63-29=34
Answer:
The middle number would be (14+15)/2 = 14.5
How I found that is I did (14+15)/2.
pls mark as branliest
