Answer: 96 units

Step-by-step explanation:

3 by 4 Right Triangles: $(3*4)/2$ for <em>each </em>triangle, so $2((3*4)/2)=12$ units for both two triangles.

Middle Rectangles:<em> </em>Since all of the 3 rectangles have the same height, we can add together the widths to get $(3+4+5)*7=12*7=84$ units.

Add them together: $84+12=96$ units

I hope it helps!

Solve each equation 3m-3/5=2m-1/2

Kazeer [188]

Answer:

m= 1/10

Step-by-step explanation:

1. Move the terms so that will be 3m - 2m=-1/2 + 3/5

2. Subtract the m values so that will be 3m - 2m= 1 or m

3. Calculate the sum.

4. So the answer will be m= 1/10. M because we subtracted 2 from 3 which make us 1 so we say it m and 1/10 by doing 1/2 + 3/5.

M(6, 6) is the midpoint of . The coordinates of S are (8, 9). What are the coordinates of R?

Sidana [21]

$\bf \textit{middle point of 2 points }\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
R&({{ x}}\quad ,&{{ y}})\quad 
% (c,d)
S&({{ 8}}\quad ,&{{ 9}})
\end{array}\qquad
% coordinates of midpoint 
\left(\cfrac{{{ x_2}} + {{ x_1}}}{2}\quad ,\quad \cfrac{{{ y_2}} + {{ y_1}}}{2} \right)$

$\bf \left( \cfrac{8+x}{2}~~,~~\cfrac{9+y}{2} \right)=\stackrel{midpoint}{M(6,6)}\implies 
\begin{cases}
\cfrac{8+x}{2}=6\\\\
8+x=12\\
\boxed{x=4}\\
----------\\
\cfrac{9+y}{2}=6\\\\
9+y=12\\
\boxed{y=3}
\end{cases}$
