the answer is C
Use the distributive property
Step-by-step explanation:
(x+2y)²=x²+4xy+4y²
...........
Answer:
-1
Step-by-step explanation: from the equation, x-y=8, make y the subject of the formulae , this gives - y= -x +8
divide all through by (-) sign, this gives y= x - 8
from the last equation above, the slope is the coefficient of x which is 1. since it is perpendicula, the answer is -1
by co efficient, we mean the number multiplying the unknown
Answer:
They are similar.
Step-by-step explanation:
They are similar because, the top triangle has one more square to the height as well as the width. If you take one square away from the height and width the top triangle is the same size as the bottom triangle.
Answer:
x - y is also a rational number. Hence satisfies the closure property.
Step-by-step explanation:

Closure property of subtraction states that for any two integers a and b, (a - b) must also be an integer.
Here x and y are rational numbers. so x - y must also be rational to satisfy the closure property.
