Answer:

(x-8)(x+3) = x² - 5x -24

Step-by-step explanation:

We need to find the product of binomials (x-8)(x+3).

Let us use the distribution property.

    (x-8)(x+3)=x\times x+x\times 3-8\times x-8\times 3\\(x-8)(x+3)=x^2-5x-24

So

        (x-8)(x+3) = x² - 5x -24

Find c.
Vinvika [58]
<h3>Answer:   0.5</h3>

========================================================

Explanation:

The ultimate goal is to find the value for lowercase c, or find the length of side c. So we'll use the portion sin(C)/c as part of the law of sines.

We don't know the value of lowercase 'a', so we'll ignore the sin(A)/a portion.

This leaves sin(B)/b

We see that one side is 2 cm long, so this means b = 2. The angle opposite this is 105 degrees, so B = 105.

The angle opposite side c is 15 degrees, so C = 15.

The lowercase letters represent side lengths, while the uppercase letters are angles.

--------------------------

We have enough to apply the law of sines to solve for side c.

sin(B)/b = sin(C)/c

sin(105)/2 = sin(15)/c

c*sin(105) = 2*sin(15) ............. cross multiply

c = 2*sin(15)/sin(105) .............. dividing both sides by sin(105)

c = 0.53589838486224

c = 0.5

Side c is roughly 0.5 cm long.

Make sure your calculator is in degree mode.

HELP!!! <br><br> Which function shows a fabric with a price of $1.25 per square yard?
ohaa [14]

Answer:

y=1.25x

Step-by-step explanation:

Let us assume that,

x represents the number of sq. yards of fabric and

y represents price of the fabric.

As the unit price of the fabric i.e cost per sq. yard of fabric is $1.25, so for each number of sq. yard of fabric, the cost for that much of fabric will be multiple of 1.25 of that number.

i.e y=1.25x

Here, the rate of change is 1.25. So for each increase in x, the amount of increase in y is 1.25

The table along with the graph have been attached below.
