All you do is distribute you multiply x x 4 then 5 times 4 and then you divide 20 by 4 then x equals 5
Answer:
x=\frac{0.48+\sqrt{0.0768}}{0.0096},\:x=\frac{0.48-\sqrt{0.0768}}{0.0096}
Step-by-step explanation:
(x-50)^2 is x^2+2500-100x*.0048 is .0048x. 2500*0.0048 is 12, and -100*0.0048=-.48.
So, we have .0048x^2+12-.48x+6, which is
.0048x^2+18-.48x=10. USing the quadratic formula, we get
x=\frac{0.48+\sqrt{0.0768}}{0.0096},\:x=\frac{0.48-\sqrt{0.0768}}{0.0096}

Answer:
x^2+12x+27
Step-by-step explanation:
The area of the blue is
x*x = x^2
The area of the pink is
9x
The area of the green is
3x
The area of the orange is
3*9 = 27
Add them together
x^2 +9x+3x+27
Combine like terms
x^2+12x+27
