Answer:
Just add all of the amount that is given
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
Answer:
-28x -16 is the simplified answer.
Step-by-step explanation:
You have to move your constants towards your constants. So -9x and -19x are constants because their variable is the same. SO -9x plus -19x is -28x. And -33 and 17 are constant because they have the same variable so -33 plus 17 is -16. You can recheck my math to make sure.
