The figure shown is made up of a square and a triangle. Express the area of the figure in terms of y.

Doss [256]

Answer:

$y^2+2y$

Step-by-step explanation:

The area of a square can be found by $s^2$ and the area of a triangle can be found by $\frac{1}{2}b*h$ .

The area of the square with side length y is $y^2$ .

The area of the triangle with the base 4 and height y is $\frac{1}{2}4*y = 2y$

Adding the areas together gives $y^2+2y$

-1\2x+1y=3/4, y-2x=3 , do I divide all the fractions by 4 to get rid of the fraction or by 2?

Law Incorporation [45]

You multiply both sides of the first equation by 4.
Then you have . . .
-2x + 4y = 3 and y - 2x = 3 .

If you want to get rid of a fraction, you multiply it by itsdenominator.
BUT ... whatever you do to one term on one side of the equation, you
have to do the same to all the terms on that side, AND then you have to
do the same thing to all the termson the OTHER side.
