Answer:
4xy
Step-by-step explanation:
2 x 2 = 4, then just plop the x and y down, and there's your answer
Answer:
Step-by-step explanation:
y = (x+1)² - 3
= (x²+2x+1)-3
= x²+2x-2
:::::
y = (x-2)² + 3
= (x²-4x+4) + 3
= x²-4x+7
a= 16x+16
b= 40x + 15
Step-by-step explanation:
We know that perimeter of a rectangle is

So therefore



Answer= A) that is perimeter is 16x+16
We know that area of a rectangle is l×b
So therefore


Answer = b) that is area is 40x + 15
