Answer: 2) 4x - 8 - 8y
Step-by-step explanation:
if xy=4
then y(x-4)(x+2) use foil method with parenthisies to get
y(x²+2x-4x-8) foil again
x²y+2xy-4xy-8y plug 4 in for xy
x²y+2(4)-4(4)-8y solve what u can
x²y+8-16-8y= x²y-8-8y
for x²y if you take out the exponent you have an xy and an x so when u plug in 4 you get 4x ending up with a solution of
4x-8-8y
Hope that helped
Answer:
1) triangles are similar
Step-by-step explanation:
The height from vertex X of isosceles ∆WXY is 4 units. The width WY is also 4 units. In isosceles ∆UVW, the height from vertex V is 6 units, and the width UW is also 6 units.
The height ratios are ...
∆WXY/∆UVW = 4/6
The width ratios are ...
∆WXY/∆UVW = 4/6
The measures of ∆WXY are proportional to those of ∆UVW, so the triangles are similar.

Strictly speaking, you cannot go by triangle height and width alone. That is why we made not of the fact that the triangles are <em>isosceles</em>. When base and height of an isosceles triangle are proportional, the Pythagorean theorem guarantees that side lengths are proportional. Trigonometry can also be invoked to support the claim that angles are congruent.
Take the co-ordinates of your triangle and add three to the Y co-ordinates and keep the X co-ordinates the same. Then, graph. The shape should have slid upwards three points.
