miskamm [114]

Answer:

L=1+20i

B=3+20i

Step-by-step explanation:

From the question we are told that:

Area A=440cm^2

Generally the equation for For Area is mathematically given by

 A=L*B

 A=x*(x-2)

Therefore

 x^2-2x-440=0

 x=1+20i

Therefore The Dimensions are

  L=1+20i

 B=1+20i+2

 B=3+20i

Determine whether the system of equations has no solution, one solution, or infinitely many solutions
Vinil7 [7]

Answer:

one solution

Step-by-step explanation:

y=-3x+5

y=1/2x-2

You can tell straight off the bat, it does have a solution, and it isn't infinite solutions. If it had no solution, it would have the same slope but different y-intercepts. If it had infinite solutions, the 2 equations would have to be the exact same. So there is only one solution.

hope it helps

The formula for the perimeter of a rectangle is p=2l 2w. solve for w. w=p−2l/2 w=2p/l w=p 2l w=2p−l
TiliK225 [7]
p=2l+2w\ \ \ \ \ |subtract\ 2l\ from\ both\ sides\\\\2w=p-2l\ \ \ \ |divide\ both\ sides\ by\ 2\\\\\boxed{w=\dfrac{p-2l}{2}}
