Step-by-step explanation:

The ratio of the perimeters = the scale

P₂ / P₁ = 6 / 4 = 3 / 2

The ratio of the areas = the square of the scale

A₂ / A₁ = (6 / 4)² = (3 / 2)² = 9 / 4

Same for the triangles:

P₂ / P₁ = 6 / 3 = 2

A₂ / A₁ = (6 / 3)² = (2)² = 4

I don't understand how to find the product of (x-3y)(2x+3y)

WINSTONCH [101]

Hey, okay, so you just FOIL it.
F - first, O - outside, I - inside, L - last.
multiply x&2x, x&3y, -3y&2x, -3y&3y.
So it should look like this:

2x^2+3xy-6xy-9y
so the final answer should be
2x^2+3xy-9y

If Fred feeds 12 horses for two weeks with 25 bales of hay, how many bales of hay does he need to feed 15 horses for two weeks?

Dvinal [7]

Answer:

He needs 31.25 bales of hay to feed 15 horses for two weeks

Step-by-step explanation:

This question can be solved using a rule of three.

25 bales of hay feed 12 horses. How many feed 15 horses?

12 horses - 25 bales of hay

15 horses - x bales of hay

$12x = 25*15$

$x = \frac{25*15}{12}$

$x = 31.25$

He needs 31.25 bales of hay to feed 15 horses for two weeks
