Please Help I will make correct answer BRAINLIEST I PROMISE.......

Mamont248 [21]

Answer:

The correct option is 3.

Step-by-step explanation:

It is given that the length of a rectangle is represented by the function

$L(x)=4x$

The width of that same rectangle is represented by the function

$W(x)=7x^2-4x+2$

The area of a rectangle is

$A=length \times width$

$A=L(x) \times W(x)$

$(L\cdot W)(x)=L(x) \times W(x)$

$(L\cdot W)(x)=4x\times(7x^2-4x+2)$

$(L\cdot W)(x)=28x^3-16x^2+8x)$

Therefore option 3 is correct.

A pair of shoes usually sells for $61. If the shoes are 20% off, and sales tax is 5%, what is the total price of the shoes, incl

lana [24]

You first multiply $61 by .20(decimal form of 20%) and get $12.2

Since this is 20% off(that means it's less than the original price) so subtract 12.2 from $61=48.8

then add the tax so 48.8 by .05 =2.44

so 48.8+2.44

the final price is $51.24

Look at the image given, order the set of numbers from Least To Greatest! (1/2) there are some fraction answers

IRINA_888 [86]

Answer:

-13/4, -3, 16/5, 5

Step-by-step explanation:

-13÷4= -3.25

-3=-3

16÷5=3.2

5=5

For -13/4, you can just take away the negative symbol and do 13÷4, then add it on for 3.25. That does not work for every problem like this though.

Please give brainliest if I helped! :)
