Convert to the product of multiplication<br>a^2-b^2-4b-4
kirill [66]

a^2-b^2-4b-4 in form of multiplication is  (a-b)(a+b)-4(b+1) .

<u>Step-by-step explanation:</u>

We know that factors are the numbers that are being multiplied together . As 6532*7 = 45724 .Here 6532 & 7 are the factors and 45724 is product of the factors .

Here , we need to convert to the product of multiplication

a^2-b^2-4b-4 or , a^2-b^2-4b-4 :

⇒  a^2-b^2-4b-4

We know by identity that , p^2-q^2 = (p-q)(p+q)

⇒  (a-b)(a+b)-4b-4

Taking common term out as -4 :

⇒  (a-b)(a+b)-4(b+1)

Therefore  , a^2-b^2-4b-4 in form of multiplication is  (a-b)(a+b)-4(b+1) .

Simplify 4+ (-3) - 2 * (-6)<br> A.-11<br> m<br> 3<br> g
mr Goodwill [35]

Answer:

13

Step-by-step explanation:

4+(-3)-2*(-6)

Let us start from the left

2*(-6)= 2 times 6 , where we will have a negative sign on the result as + when multiplied by - gives - (negative)

2*(-6)=-12

4+(-3)-2*(-6) = 4+(-3)-(-12)

Now we open the bracket from the left. It the sign outside the bracket is negative the sign in the bracket will be changed

Hence

4+(-3)-(-12)= 4-3+12

Now -3 +12 we find the difference as the signs are opposite and then place the sign with the larger number

Hence -3+12=9

4-3+12=4+9 = 13

Jill Barley obtained a 25-year, $60,000.00 mortgage loan from University
kari74 [83]

Answer:

a. Interest = $300

b. Payment to principal = $86.40

c. New balance = $‭59,913.6‬0

Step-by-step explanation:

The monthly payment has both an interest component and a principal repayment component.

The interest component is based on the total principal still due at the time and the principal repayment component will be the rest of the payment.

As the interest is listed in annual terms, it needs to be made a monthly rate:

= 6%/12 months

= 0.5%

Interest = 60,000 * 0.5%

= $300

Payment to principal = 386.40 - 300

= $86.40

New balance = Amount due - payment to principal

= 60,000 - 86.40

= $‭59,913.6‬0
