ANSWER

80 units²

EXPLANATION

One way to solve this is to find the area of the blue square and the subtract the areas of the red triangles:

The blue square is 12 units long by 12 units wide. Its area is:

$A_{\text{square}}=12\times12=144$

Then, the area of the big triangle, which has a base 12 units long and a height of 10 units, is:

$A_{\text{traingle}1}=\frac{12\times10}{2}=\frac{120}{2}=60$

The smaller triangle has a base of 4 units and a heigth of 2 units. Its area is:

$A_{\text{triangle}2}=\frac{4\times2}{2}=\frac{8}{2}=4$

So the total area of the figure is:

$\begin{gathered} A=A_{\text{square}}-A_{triangle1}-A_{triangle2} \\ A=144-60-4 \\ A=80 \end{gathered}$

Please help! What is the slope of the line graphed on the coordinate plane?

Lisa [10]

Answer:

The slope is 3/4

Step-by-step explanation:

You can Y2-Y1/X2-X1 to find the answer to this question

Since the points are (-2,3) and (2,6) it will be..

6-3/2+2 ** the 2 becomes a plus in the denominator because negative and negative is positive

3/4 is the slope
