Answer:

5a^2+12b^2-40b

Step-by-step explanation:

First distribute the -4 to the 2b and -3b. This leaves you with 5a^2-8b+12b(b+4)

Now you can distribute the 12b to b and +4. This leaves you with 5a^2-8b+12b^2+48b

Now you can combine your like terms leaving you with 5a^2+12b^2-40b.

How can you use the multiplication property of equality to rewrite the equation 0.6x+4.8=7.2 so that the numbers in the problem
Mars2501 [29]

We are given the equation:

0.6 x + 4.8 = 7.2

 

In this case, the multiplication property of equality states that whatever is multiplied on one side should also be multiplied on the other side. Now we need to find the number that will make everything a whole number, in this case 5. Multiply everything by 5:

5 * (0.6 x + 4.8 = 7.2)

3 x + 24 = 36

However we can see that we can still further simplify the equation by multiplying everything by 1/3:

(1/3) * (3 x + 24 = 36)

x + 8 = 12

or

x = 4

To find the amount of money you pay for tax, you have to multiply the price of the product by the percentage of the tax, then divide it by 100. in this case, 76x5.6=425.6/100=4.256 which is $4.26 (to the nearest cent)
