Answer:

203

Step-by-step explanation:

First, the square is 49m².

The areas of the triangles are A= 1/2 bh

1/2 (77), which is 38.5m² each.

Then multiply 38.5 by 4, which is 154.

Then add 154 plus 49, which is 203.

Write the slope-intercept form of the equation of the line 3x - 2y = -16

denis-greek [22]

We will solve for y.
$-3x-16=-2y$

Divide both sides by -2
$y=\frac{3}{2}x + 8$

<u>Slope-intercept form</u>
$y=\frac{3}{2}x + 8$
