PLEAZE HELP IM FAILING THIS CLASS 9) The volume of a box is represented by x' +11x² + 20x – 32. The width of the box is x – 1, and
the height is x + 8. Find the expression representing the length of the box.

Answers

Answer:

Step-by-step explanation:

Volume of the box  =  x³ +11x² + 20x – 32        I think the ' is a typo for ³

      the width is x-1    and the height is x+8      

Find an expression for the length

       Vol = LWH    solve L

        Vol / (WH)   =  L     so

L  =  (x³ +11x² + 20x – 32) / (x-1) (x+8)      

                    so it would help to factor the numerator

       (x³ +11x² + 20x – 32)       I'm willing to bet (x-1) and  (x+8) are factors

                                               but I will plot the equation to find the three roots

        (x³ +11x² + 20x – 32)  = (x-1) (x+8) (x+4)

L  =  (x³ +11x² + 20x – 32) / (x-1) (x+8)

   =  (x-1) (x+8) (x+4) / (x-1) (x+8)           the (x-1) and (x+8) cancel out leaving

L =   (x + 4)

You are a dress maker and buy many of your fabrics overseas. You have been given a new design for a dress that each dress
takes 1.5 metres of fabric that you need to buy from a supplier. You are making 12 dresses. The fabric is sold for $22.50 per
yard. How many yards would you need to order and what would it cost you?

Answers

Answer:

Total yards = 19.685 yards

Total cost = $442.9125

Step-by-step explanation:

Fabrics per dress = 1.5 meters

Number of dresses = 12

Total fabrics needed = 1.5 meters × 12

= 18 meters

Convert 18 meters of fabrics into yards

18 meters = 19.685 yards

Cost of fabric per yard = $22.50

Total cost of fabrics in yards = 19.685 yards × $22.50

= $442.9125

Using the information that
5.2 x 67 = 348.4
write down the value of

c) 348.4 ÷ 52​

Answers

Answer: 6.7

Step-by-step explanation:

We know that:

5.2*67 = 348.4

And we want to find the value of:

348.4/52 = x

So, let's return to the original equation.

5.2*67 = 348.4

Let's try to "construct" the quotient 348.4/52

The first step is to divide both sides by 5.2, then we get:

(5.2*67)/5.2  = 348.4/5.2

67 = 348.4/5.2

Now we have 5.2 in the denominator instead of 52, then we can divide both sides by 10 to get:

67/10 = ( 348.4/5.2)/10 = 348.4/(5.2*10) = 348.8/52

6.7 = 348.8/52

Then the solution to the quotient:

348.4/52 is 6.7​

Show the steps of solving. a) 6x - 2y = 28
4x + 2y = 12

PLEASE HELPPPPP I’ll give brainlist!!!

Answers

Answer:

x = 4 and y = -2

Step-by-step explanation:

Let 6x - 2y = 28 be equation (i)

and 4x + 2y = 12 be equation (ii)

To solve the following equations, first add the equations:

6x - 2y + 4x + 2y = 28 + 12

6x + 4x + 2y - 2y = 28 + 12

10 x = 40

x = 4

Substituting in (ii)

4x + 2y = 12

4*4 + 2y = 12

2y = 12 - 16

2y = -4

y = -2
