<u>formula: </u>
(a+b)^2
= a^2+2ab+b^2
Here, we have x^2 (as in a^2)
and -6x (as in 2ab), which, we're missing the b^2
(I'm not really sure how to describe this but bare with me)
-6/2 (-6 is from the -6x) = -3 (the b)
-3^2 = -3*-3 which is equal to 9 (positive 9)
Writing it out -
x^2-6x+9 = -5
- Addition of inequality -
Since we add 9 to the left side, we have to add 9 to the right side; which gives us:
x^2-6x+9=4
Next, lets put the x^2-6x+9 as in (a+b)^2:
(x-3)^2 = 4
<em>Then let's do the square root of equality (square rooting both sides) :</em>
<u>x-3 = 2</u>
<em>Finally lets add 3 to both sides</em>
<u>x = 5</u>
THE ANSWER IS <u><em>x=5</em></u>

Sebastian went up 7 floors not down so it shouldn't be -7 and he went down 9 floors so it should be 7-9
6/7 because it’s a smaller fraction with more pieces. Brainliest???
80 oz .. One pound is 16 oz if there is 5 pounds then you just multiply 16x5 and get 80 ounces
So the equation is parallel and the slope will be 2
y=2x+b
sub in(5,4) for x and y to find b
4=2(5)+b
4-10=b
b=-6
therefore the equation is y=2x-6
