Answer:

The sixth number in series is 13.

Step-by-step explanation:

Given series : 3, -6, 12, 4, 20, ?

The pattern followed by the series is:

The first number = 3

Second number = 3 - 9 = - 6

Third number = - 6 + (9 ×2) = -6 + 18 = 12

Fourth number = 12 - 8 = 4

Fifth number = 4 + (8 ×2) = 20

Sixth number = 20 - 7 = 13

Seventh number = 13 + (7 ×2) = 13 + 14 = 27 and so on.

So as per the above pattern, the sixth number in the series is 13.

Answer: 9 pack for $4.50

To find a unit price, you need to divide. ($3.79 by 6, $4.50 by 9, etc.)

Once you find the answers to the division problems, pick the one which is the least, which is $0.5 out of the others which were $0.63 and $0.57. Therefore, the 9 pack for $4.50 package is the least per bottle, $0.5 per bottle to be exact.

Hope this helps!

The perimeter P of a square (measured in inches) is expanding in size at a constant rate of change of 4 inches per inch with res

vivado [14]

Answer:

a. 10 inches

b. 8 inches

c. $\frac{dP}{ds} = 4$

Step-by-step explanation:

a. At side 0, perimeter is 0*4 = 0 in. At side 2.5 inches, perimeter = 2.5*4 = 10 inches, a change of 10 - 0 = 10 inches

b. At side 1, perimeter is 1*4 = 4 inches. At side 3 inches, perimeter = 3*4 = 12 inches, a change of 12 - 4 = 8 inches.

c. We can express the change in the square's perimeter P in terms of the change in the square's side length s as

$\frac{dP}{ds} = 4$

What is the product? (3x-6) (2x^2 -7x+1)

STALIN [3.7K]

Answer-

$\left(3x-6\right)\left(2x^2-7x+1\right)=6x^3-33x^2+45x-6$

Solution-

Given the two polynomials are $3x-6, 2x^2 -7x+1$

So their product will be,

$=\left(3x-6\right)\left(2x^2-7x+1\right)$

Distributing the Parentheses,

$=3x\cdot \:2x^2+3x\left(-7x\right)+3x\cdot \:1+\left(-6\right)\cdot \:2x^2+\left(-6\right)\left(-7x\right)+\left(-6\right)\cdot \:1$

Applying minus-plus rules,

$=3\cdot \:2x^2x-3\cdot \:7xx+3\cdot \:1\cdot \:x-6\cdot \:2x^2+6\cdot \:7x-6\cdot \:1$

Simplifying further,

$=6x^3-33x^2+45x-6$
