H=-3x^2-6x+5 subtract 5 from both sides
h-5=-3x^2-6x divide both sides by -3
(5-h)/3=x^2+2x halve the linear coefficient, square it, add it to both sides....
(2/2)^2=1 add 1 to both sides...
(5-h+3)/3=x^2+2x+1, now the right side is a perfect square...
(8-h)/3=(x+1)^2 multiply both sides by 3
8-h=3(x+1)^2 divide both sides by -1
h-8=-3(x+1)^2 add 8 to both sides
h=-3(x+1)^2+8
h(x)= -3(x+1)^2+8
Second answer down from the top :)
.7 and 7 are related because:
-If you move the decimal point left or right depending, they are the same number.
-They both stand for a value.
-They are both rational. They can both be put into a ratio or fraction.
I hope this helps!

Answer:
700 square feet
Step-by-step explanation:
The total area of two units is 2×(840 ft²) = 1680 ft². Of that area, 980 ft² is allocated to kitchen and bath, so the remaining ...
1680 -980 = 700 . . . square feet
will be the area of the two bedrooms. The area of each bedroom is half that amount.
350 square feet of carpet is needed for each bedroom.

Simplify the left side.
-0.25x = 10
Divide each side by -0.25.
x = -40
