Answer:

$2x(x + 1) - 2 = 2(x - 3)(x + 3) \\ = > 2 {x}^{2} + 2x - 2 = 2( {x}^{2} - {3}^{2} ) \\ = > 2 {x}^{2} + 2x - 3 = 2 {x}^{2} - 2(9) \\ = > 2 {x}^{2} + 2x - 3 \: is \: not \: equal \: to \: 2 {x}^{2} - 1$

A rectangle is twice as long as it is wide. Its area is 72 square units. Find the length of each side. System of equations

liraira [26]

Answer:

L = 12

W = 6

Step-by-step explanation:

W = 2L

A = L * W

A = 72

72 = L * 2L

72 = 3L

24 = L (you have to divide by 2)

L = 12

W = 6

como calcular la cantidad de horas por proyecto si un contratista tiene 5,000 horas-hombres y el costo es de $10 y $12 por proye

Tju [1.3M]

Answer:

Each project has 2.500 man-hours

Step-by-step explanation:

Available man hours: 5000

For two projects Costs $

X: project A 10

Y: project B 12

Approach:

X + Y = 5000 => X = 5000 - Y

10 * X + 12 * Y = 55000

replacing:

10 * (5000 - Y) + 12 * Y = 55000

50000 - 10 * Y + 12 * Y = 55000

2 * Y = 55000 - 50000

Y = 5000/2

Y = 2500

For X:

X = 5000 - 2500

X = 2500

The number of hours available for each project are:

Projects Man hours

X: project A 2500

Y: project B 2500

Note: Consider we need to find the factor form of the given expression by taking out the GCF.

Given:

The expression is:

$-42k^3+24k^4+12k^5$

To find:

The factor form of the given expression.

Solution:

We have,

$-42k^3+24k^4+12k^5$

It can be written as:

$=6k^3(-7)+6k^3(4k)+6k^3(2k^2)$

Taking out the greatest common factor (GCF), we get

$=6k^3(-7+4k+2k^2)$

Therefore, the factor form of the given expression is $6k^3(-7+4k+2k^2)$ .
