Intercept at, y=0 and at x=0
-3(0)+5(y)=60
y=12 , z= 30, (y intercept) or (0,12,30)

-3(x)+5(0)=60
x=-20,z=30, (x intercept) or (-20, 0, 60)

Answer:

156 inches^2

Step-by-step explanation:

The area of a triangle is 1/2 base x height

All of the triangles have a base of 6 inches and a height of 10 inches.

so 1/2 6 x 10= 30

There are 4 triangles with an area of 30 square inches

and then the square in the middle has a length of 6 in and a width of 6 in so it has an area of 36 in^2

so in total you would have 30+30+30+30+36, or 156

A rectangle is dilated by a scale factor of y to create a new rectangle. The area of the new rectangle is y2 times the area of t

slamgirl [31]

Answer: True

Step-by-step explanation:

Suppose the length and width of the original rectangle is L and W

After dilation by a factor of y, it becomes yL and yW

Area of the original rectangle $A_1=L\times W$

The area of the dilated rectangle is $A_2=yL\times yW=y^2LW$

we can see that

$\Rightarrow A_2=y^2A_1$
