Write the equation in standard form using factoring. f(x) = (2x + 1)(x – 4)

Mathematics

ArbitrLikvidat [17]3 years ago
7 0

Answer:

<em>2x^2 - 7x - 4</em>

Step-by-step explanation:

Given the expression f(x) = (2x+1)(x – 4)

To write it in standard form, we need to factorize it

(2x+1)(x – 4)

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

= 2x^2 - 8x + x - 4

= 2x^2 - 7x - 4

<em>hence the expression in standard form is 2x^2 - 7x - 4</em>

the length of a rectangular picture frame is 3 centimeters less than twice the width. the perimeter is 78 centimeters. find the
Natalka [10]
Let the width be x
width = x
length = 2x - 3

Perimeter = x + 2x - 3 + x + 2x - 3 = 6x - 6 

6x - 6 = 78
6x = 78 + 6
6x = 84
x = 14 cm

2x - 3 = 2(14) - 3 = 25cm

The width is 14cm and the length is 25cm

h = a/b
h = 70.8/9.44
h = 7.5

A normal distribution has a mean of 4 and a standard deviation of 1. What percent of values are from 4 to 7?
Igoryamba

Answer:

49.865%

Step-by-step explanation:

Given that:

μ = 4 ; σ = 1

For x = 4

P(x < 4) :

Z score (x - μ) / σ

P(x < 7) - P(x < 4)

((7 - 4) / 1) - ((4 - 4) / 1)

P(Z < 3) - P(Z < 0)

Usibg the Z probability calculator :

0.99865 - 0.5

= 0.49865

= 0.49865 * 100

= 49.865%

Khianna says that she found a shortcut to calculate the surface area to volume ratio.
GREYUIT [131]
The process works well for a cylinder. It will not work for any other 3-D figures.

_____
I haven't needed to use a method, so there is no comparison.

If you are asked to find the area and volume, then the area/volume ratio, usually you will do it in that order. The "shortcut" is only useful if you don't need either volume or surface area as part of the answer to the question.
