Answer: 4a^2(8a+3)

Step-by-step explanation:

The given algebraic expression : 32a^3 + 12a^2

Here , the prime factorization of 32a^3 \text{ and } 12a^2 are:

32a^3=2\times2\times2\times2\times2\times a\times a

12\ a^2=2\times 2\times 3\times a\times a

Greatest Common factor (GCF)= 2\times2\times a\times a= 4a^2

Taking the GCF out of the each term of the expression , we get

32a^3 + 12a^2\\\\=4a^2\times 8a +4a^2\times 3\\\\=4a^2(8a+3)

Hence, the fully factored form of 32a^3 + 12a^2=4a^2(8a+3)

Solve the equation, and check the solutions (√x+3)+6=3.
larisa86 [58]

Answer:

The equation has no solution.

Step-by-step explanation:

Hi there!

First, let´s write the equation:

(√x + 3) + 6 = 3

To solve the equation, let´s subtract 6 to both sides of the equation:

√x + 3 = -3

subtract 3 to both sides of the equation:

√x = -6  (the square root of any number can´t be negative, but let´s solve it anyway and then check the solution).

Square both sides of the equation:

x = 36

Now, let´s check the solution:

(√x + 3) + 6 = 3

x = 36

(√36 + 3) + 6 = 3

(6 + 3) + 6 = 3

9 + 6 = 3

15 ≠ 3

Then, the equation has no solution.

Have a nice day!

Find the unit price
Mrac [35]

Answer:

Price per ounce is $0.062

Step-by-step explanation:

Here, we want to find the unit price in which this vase is price per ounce

Firstly, we need the total ounce value

1 pound = 16 ounce

so two pounds will be 2 * 16 = 32 ounces

So the total ounce value is 32 ounces + 8 ounce = 40 ounces

So 40 ounces = $2.48

price per ounce will be $2.48/40 = $0.062 per ounce
