It is 83 because when you plug in for x you must use ( ) so it’s (-9)^2 and that is 81. Plus 81 + 2 = 83... the first answer was a simple mistake

Andrew [12]

The function A(x) = 2x²-3x-2 represents the area of the garden.

Step-by-step explanation:

Given,

Length of rectangular garden is given by;

L(x) = 2x+1

Width of rectangular garden is given by;

W(x) = x-2

Area of rectangular garden;

A(x) = L(x) * W(x)

A(x) = (2x+1)(x-2)\\A(x) = 2x(x-2)+1(x-2)\\A(x) =2x^2-4x+x-2\\A(x) = 2x^2-3x-2

The function A(x) = 2x²-3x-2 represents the area of the garden.

KatRina [158]

Answer:

25X + 25Y = 1700

25X + 100Y = 3200

Step-by-step explanation:

Given that the principal of a high school spent $1700 for X desk and Y chairs at $25 each. Then, the equation will be

25X + 25Y = 1700 ....... (1)

If he had bought half the number of desk in twice the number of chairs he would have spent 1600. That is

25(X/2) + 25(2Y) = 1600

25X/2 + 50Y = 1600

Find the LCM and cross multiply

25X + 100Y = 3200 ........(2)
