What do I need to solve :)
I might be wrong but it should be 1
Answer:
X=10, x=4
Step-by-step explanation:
first, divide 14 by 2, and square it; giving you
x^2-14x+(7)^2=-40
Because 7^2 is 49, you have to add 49 to the other side; giving you
x^2-14x+(7)^2=9
Then factor the left side; giving you (x-7)^2=9
Take the square root of both sides, giving you
(x-7)^2= plus or minus 3
Then solve to get two solutions, 10 and 4
2(3x-5) + 2(-2x+10)
6x-10 + -4x+ 20
=2x+ 10
The first one
Running forward is adding
Running opposite direction is subtracting
5-5
5-6
6-5
6-0
5-5 is the only one that equals 0
