Answer:

B

Step-by-step explanation:

2 walls are 30 x 9 and 2 walls are 20 x 9 and there are 4 units

30 x 9 = 270, 20 x 9 = 180

4(2)(270) + 4(2)(180) = 3600, so the answer is B

Write an equation in point-slope form and slope-intercept form for

Alex787 [66]

Answer: y=2x-1

Step-by-step explanation:

Equation of a line that passes through (a,b) and have slope m is given by :-

$(y-b)=m(x-a)$ [point slope form]

Given, Point = (4,7) , m= 2

Equation in point slope form : $(y-7)=2(x-4)$

To write in slope intercept form (y=mx+c) , we need to simplify it

$y-7= 2x-8\\\\\Rightarrow\ y-2x=-8+7\\\\\Rightarrow\ y-2x=-1\\\\\Rightarrow\ y=2x-1$

Hence, y=2x-1

Using the quadratic formula to solve x2 + 20 = 2x, what are the values of x?

zheka24 [161]

$\bf{Hey\ there!}$

$\bf{Quadratic\ formula\ is:}$ $\bf{x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}} \ or \ you\ could\ say\ ax^2+bx+c=0$

$\bf{\bullet\ First: subtract\ by\ 2x\ on\ your\ sides\ that\ you're\ working\ with}$

$\bf{Like:x^2+20-2x=2x-2x}$

$\bf{We\ get:x^2-2x+20=0}$

$\bf{\bullet \ a=1}\\ \bf{\bullet \ b=-2}\\ \bf{\bullet \ c=20}$

$\bf{x=\frac{-(-2)\pm\sqrt{(-2)^2-4(1)(20})}{2(1)}$

$\bf{(-2)^2-4(1)(20)=-76} \\ \\ \bf{2(1)=2}$

$\bold{-(-2)=-1(-2))=+2}$

$\bf{x=\frac{2\pm\sqrt{-76}}{2}}$

$\bf{Thus\ there\ is\ NO\ REAL\ SOLUTIONS}$

$\text{Good\ luck\ on\ your\ assignment\ and\ enjoy\ your\ day!}$
