You take the three zeros and put them back with the x s

(x-6)(x+5)(x-2) they are reversed when you put them back in

multiply the first two and get $x^2+5x -6x-30(x-2)$
simplify to $x^2-x-30(x-2)$

Multiply it out again and get $x^3-x^2-30x-2x^2+2x+60$
finally simplify and get $x^3-3x^2-28x+60$

So the answer is the first one

A rectangle has a length of 4x plus 5 and a width of 8x minus 4. Which expression shows the perimeter of that rectangle? A: 4x +

mezya [45]

Answer: The answer is (D) $24x+2.$

Step-by-step explanation: Given that there is a rectangle, where length of the rectangle is given by

$\ell=4x+5,$

and width of the rectangle is given by

$b=8x-4.$

We are to find the perimeter of the rectangle. To do so, we need to add two times length with two times breadth of the rectangle.

Therefore, perimeter is given by

$p=2\ell+2b=2\times(4x+5)+2\times(8x-1)=8x+10+16x-8=24x+2.$

Thus, the correct option is (D).

The stem plot shows the number of sit-ups completed by a group of gym members in one minute. Row1 with a 1 to the left of the ba

allochka39001 [22]

Answer:

Only statement second is correct about the distribution.

Step-by-step explanation:

The stem plot data given to us is;

1 | 9

2 | 5

3 | 4 6 8 8

4 | 0 3 6 7 7

5 | 0 0 1 2

As it is given in the question that 1 | 9 = 19 sit-ups, so the data value are;

19, 25, 34, 36, 38, 38, 40, 43, 46, 47, 47, 50, 50, 51, 52

(a) The first statement that there is one outlier in the distribution is false as there are two outliers in the data (19 and 25) as they are very far from the rest of the data.

(b) The statement that the distribution is skewed left is correct because the tail of the distribution is towards the left.

(c) The statement that the center is around 47 is false as the center or mean of the data is 43 because the middle most data value is 43.

(d) The statement that the distribution is bimodal is false as there are is three modes in the data (38, 47 and 50), so the given distribution is trimodal.
