All except the third, because when you distribute the three you get 15w+24 that is equivalent to -3(-5w-8).

the length of marshalls retangular poster is 2 times the width if the perimeter is 24 inches what is the area

Ilia_Sergeevich [38]

Let us assume the width of the rectangle = x
Then
The length of the rectangle = 2x
The perimeter of the rectangle = 24 inches
We know the formula of the perimeter of a rectangle is
Perimeter = 2 (length + Breadth)
24 = 2 (2x + x)
24 = 2 * 3x
24 = 6x
x = 24/6
= 4
So the width of the rectangle = 4 inches
length of the rectangle = 2x
= 2 * 4 inches
= 8 inches
Now
The Area of the rectangle = Width * Length
= 4 * 8 inches^2
= 32 inches ^2
So the area of the rectangle is 32 square inches. I hope i have helped you.

Really need some help

Viefleur [7K]

The outer exponent is 4 so there will be 5 terms all together. By rules of exponents

C(4,0)(3^4)(2^0)(x^8)(y^0) + C(4,1)(3^3)(2^1)(x^6)(y^3) + C(4,2)(3^2)(2^2)(x^4)(y^6) + C(4,3)(3^1)(2^3)(x^2)(y^9) + C(4,4)(3^0)(2^4)(x^0)(y^12)

The coefficient of the 3rd term: C(4,2)(3^2)(2^2) = 6 x 9 x 4 = 216

A company gives each worker a cash bonus every Friday, randomly giving a worker an amount with these probabilities: $10 - 0.75,

Shkiper50 [21]

The worker's expected weekly bonus is $30.0

<h3>How to determine the worker's expected weekly bonus?</h3>

The amounts and the probabilities are given as:

x $10 $50

P(x) 0.75 0.25

The worker's expected weekly bonus is calculated as:

$E(x) = \sum x * P(x)$

So, we have:

E(x) = $10 * 0.75 + $50 * 0.25

Evaluate the product

E(x) = $17.5 + $12.5

Evaluate the sum

E(x) = $30.0

Hence, the worker's expected weekly bonus is $30.0
