X^2-9x=-8
x^2-9x+8=-8+8
x^2-9x+8=0
(x-8)(x-1)=0
x-8=0
x-8+8=0+8
x=8
x-1=0
x-1+1=0+1
x=1
There are 2 solutions, which are 1 and 8
Answer:
23
Step-by-step explanation:
So you want to add 7x degrees and (x-4) degrees. And it will be 8x - 4 = 180 degrees because it's 180 degrees in a straight line. And you want to + the 180 by 4 because there is -4 on the other side. so it will be 8x = 184 and you just divide 184 by 8 and it will be 23 easy. if you want to my help again you can text me on instargram jason_lee093
The answer would be 22.
You would use the order of operations to solve this problem,
First you do the parenthesis, there are none so you skip this
Then the exponents, none so skip it
Then you do multiplication and division from left to right
5•7 is 35, 3•8 is 24
So the problem is now
35-24+11
After multiplication comes addition and subtraction from left to right
35-24 is 11
11+11 = 22
So the answer to (5x7)-(3x8)+11 is 22
