The area of a rectangular art studio is given by the trinomial 12x^2 + 5x - 2 What are the
nikklg [1K]

ANSWER

(3x + 2) \: by \: (4x - 1)

EXPLANATION

The area of a rectangular art studio is given by the quadratic trinomial:

12{x}^{2}  + 5x - 2

By comparing this to:

ax²+bx+c

We have a=12, b=5, and c=-2

ac=12*-2=-24

The factors of -24 that gives a sum of 5 are 8,-5

We split the middle term with these factors to get:

12{x}^{2}  + 8x  - 3x- 2

Factor by grouping,

4x(3x + 2) - 1(3x + 2) = (3x + 2)(4x - 1)

The possible dimensions are:

(3x + 2) \: by \: (4x - 1)

Carlton is solving a linear equation using the steps shown.
mario62 [17]

Answer:

D. Divide each side of the equation by –2.

Step-by-step explanation:

We have been given that Carlton is solving a linear equation using the steps shown.

Equation: -4x+12=-6x

Step 1: Add 4x to both sides: 12=-6x+4x

Step 2: Combine like terms: 12=-2x

To solve our given equation we will divide both sides of our equation by -2.

\frac{12}{-2}=\frac{-2x}{2}

-6=x

Therefore, the next step Carlton needs to complete in order to solve the equation is divide each side of the equation by –2.

A piece of string is 144 inches long. Isabel wants to cut it into 2 pieces so that one piece is five times as long as the other.
Alex Ar [27]

Answer:

  • 24 inches
  • 120 inches

Step-by-step explanation:

The lengths can be found by considering their ratio:

  short : long = 1 : 5

The sum of the ratio units is 1+5 = 6, and the sum of the lengths is 144 inches. That means each "ratio unit" stands for (144 in)/6 = 24 inches of length.

The lengths are ...

  1 : 5 = 24 in : 120 in

The pieces are 24 inches and 120 inches in length.

__

Equivalently, you can let s represent the shorter length. Then 5s is the longer one, and their total is ...

  s +5s = 144

  s = 144/6 = 24

  5s = 5(24) = 120

The lengths are 24 inches and 120 inches.
