Answer:

Step-by-step explanation:

350=12(x+20)

(divide both sides by 12)

29.1667=x+20

(subtract 20 from both sides)

x=9.16667

X (9.17) is the additional amount of money the student must save each month in order to reach his goal.

The length of the rectangle is n-3, ok, the width is 2

the area of a rectangle is just length * width

\bf A=(n-3)(2)\implies \boxed{A=2n-6}
\\\\\\
\textit{to make some equivalent, let's use our good friend Mr 1}
\\\\\\
\textit{recall that }\cfrac{whatever}{whatever}=1\qquad \qquad \cfrac{same}{same}=1
\\\\\\
\cfrac{55}{55}\cdot 2n-6\implies \cfrac{55(2n-6)}{55}\implies \cfrac{110n-330}{55}
\\\\\\
or
\\\\\\
\cfrac{xyz}{xyz}\cdot 2n-6\implies \cfrac{xyz(2n-6)}{xyz}\implies \cfrac{2nxyz-6xyz}{xyz}

so, if you simplify either of those, you'd end up with 2n-6.

because same/same = 1, and 1 * anything, is just anything itself.

Help I do not understand how to find the area of circles
kupik [55]
The formula for the area of a circle is a = <span>πr², r being the radius.

To tackle this problem, find the area of the square and then subtract the area if the circle:

Area of square = 20 * 20 = 400
Area of circle = </span><span>π(10)² = 100</span><span>π = 314

Area of square - area of circle = 400 - 314 = 86 m²

Hope this helps!
