The area of a rectangular room is 750 square feet. The width of the room is 5 feet less than the length of the room.
Gelneren [198K]

Answer:

B. y² – 5y = 750

C. 750 – y(y – 5) = 0

E. (y + 25)(y – 30) = 0

I'm assuming the 2 in the second option is supposed to be an exponent.

Step-by-step explanation:

Length = y

Width = y-5

Length × Width = Area

Area = <u>y(y-5)</u> = 750

<u>Distribute.</u>

y²-5y=750 (B is correct)

<u>If you factor the equation above</u>

(y + 25)(y – 30) = 0 (E is correct)

Area = y(y-5) = 750

<u>Subtract y(y-5) from both sides.</u>

750-y(y-5) = 0 (C is correct)

Pls help me out!! Ill be so happy!! TYSM
mr Goodwill [35]

Answer:

Hey there!

The line 4x-3y=-9 can be converted to y=mx+b form.

4x-3y=-9

-3y=-4x-9

3y=4x+9

y=4/3x+3

The slope of a line perpendicular to this line would be -3/4.

The slope of a line parallel to this line would be 4/3.

Hope this helps :)

Find a polynomial f(x) of degree 3 with real coefficients and the following zeros. 4, 2-1
natima [27]

Answer:

P(x)=x^3-5x^2+2x+8

Step-by-step explanation:

If the polynomial has the following zeros: x= 4, x=2, and x=-1, then it must have the following factors which guarantee the polynomial will render zero at the given points:

P(x)=C (x-4)\, (x-2) \,(x+1)

where C is any multiplicative constant. Since there is no other condition imposed on the polynomial, we can adopt a simple constant C = 1 to facilitate our final calculation of writing the polynomial in standard form:

P(x)=(x-4)\, (x-2) \,(x+1)\\P(x)=(x^2-2x-4x+8)\,(x+1)\\P(x)= (x^2-6x+8)\,(x+1)\\P(x)=x^3+x^2-6x^2-6x+8x+8\\P(x)=x^3-5x^2+2x+8
