Remark

The red triangle has 1/3 the side  length of    the blue triangle. So the quick answer is the missing side of the blue triangle is 66

Now no one marking this, if they require work is going to accept that quick line of reasoning, so what you have to do is set up a proportion.

Equation (proportion)

57/19 = x / 22                        Cross multiply

Solution

57*22 = 19 * x                        Divide by 19

57*22/19 = x                          Divide 19 into 57 (which is 3)

3 * 22 = x

x = 66

If the factors of function f are (x - 6) and (x - 1), what are the zeros of function f?

Answers

X=6 and x=1

You can find your zeros by determining what you have to plug into the function in order for it to equal zero

If we plug in 6, for example we’d get (6-6)(x-1)

Simplified this is 0(x-1)

Anything times 0 is 0, so this is one of our zeros.

Same goes for x-1, we just need to plug in 1 for it to equal 0

Therefore there are zeros at x=1 and x=6 :))

PLS HELP ME!! Jackie has a square wall that she covered using 130.5 square feet of fabric without any overlap. Which measurement is closest to the side length of this wall? A.11 B.26 C.32 D.65

Answers

Answer: 32

Step-by-step explanation:

A square has four equal sides.

From the question, we are informed that Jackie has a square wall that she covered using 130.5 square feet of fabric without any overlap. This simply means that the perimeter is 130.5.

Since perimeter of a square is given as 4s where s denotes the side, the side length of the wall will be:

4s = 130.5

s = 130.5/4

s = 32.625

The measurement closest to the answer is 32.

Every store employee gets an additional 10% off the already discounted price. If an employee buys an item with an original price of $40, how much is the discount? Explain how you got your answer

Answers

Answer:

$44.44444444

Step-by-step explanation:

So as per question employees get 10% discount of the discounted price. So our equation would be considering discounted price = x

=> x- 10x/100 = 40 => 100x-10x/100 = 40 => 90x = 4000 => x= $44.4444
