The volume of a rectangular box is found by multiplying its length, width, and height: V = lwh. A certain box has a volume of b

3 + 3b 2 - 4b - 12. Factor the four-term polynomial to find the dimensions of the box. Hint: Use factoring by grouping to factor the four term polynomial first.

Answer:

The dimensions of the box are (b+3), (b-2) and (b+2).

Step-by-step explanation:

The volume of a rectangular box is

V=l\times w\times h    

The volume of a certain box is

V=b^3+3b^2-4b-12

First of all find the factors of above expression by grouping method.

V=b^2(b+3)-4(b+3)

V=(b+3)(b^2-4)

V=(b+3)(b^2-2^2)

V=(b+3)(b-2)(b+2)                 [\because a^2-b^2=(a+b)(a-b)]  

Volume of a rectangle is the product of its dimensions, therefore the dimensions of the box are (b+3), (b-2) and (b+2).

Which size can of green beans shown in the table has the lowest unit price?
posledela
The can of green beans that has the lowest unit price is the 8 oz. size.

To find the unit price of each size, divide the cost by the size. (A number below that's in parentheses means it goes on forever)

0.89 ÷ 6 = 0.148(3)
1.04 ÷ 8 = 0.13
1.69 ÷ 10 = 0.169
4.79 ÷ 32 = 1496875
Among all of these answers, the can with 8 oz. has the least unit price/rate. Thus, this is the answer.

Which expression is equivalent to 5y^3/(5y)^-2​
Serggg [28]

Answer:

5^3  y^5

125 y^5

Step-by-step explanation:

5y^3/(5y)^-2​

Distribute the exponent in the denominator

5y^3/(5 ^-2 y^-2)

A negative exponent in the denominator brings it to the numerator

5y^3 5 ^2 y^2​​

Combine like terms

5 * 5^2  * y^3 5^2

We know that a^b * a^c = a^(b+c)

5^(1+2) * y^( 3+2)

5^3  y^5

125 y^5
