To solve a positive being added to a negative, just change it to the positive minus the negative. Instead of -12+7, do 7-12. So, your answer would be -5 since 12 less than 7 is negative 5.

The correct answer is 700 months .

<h3>What is simple interest?</h3>
  • Simple interest is based on the principal amount of a loan or the first deposit in a savings account.
  • Simple interest doesn't compound, which means a creditor will only pay interest on the principal amount and a borrower would never have to pay more interest on the previously accumulated interest.

Given,

         I = 105

         P = 100

            r = 0.15

Now use simple interest formula,

      S.I. = \frac{p * r* t}{100}

105=100×(0.15)×(t)

Swap sides so t is on the left.

100 ×(0.15)×(t)=105

Divide both sides by 100.

0.15t=1.05

Divide both sides by 0.15

t=700

So, we see that it takes 700 months to earn this amount.

Which expressions are equivalent to z + (z + 6)z+(z+6)z, plus, left parenthesis, z, plus, 6, right parenthesis?
Natalija [7]

Answer: 2z^{2} + 14 z +6 and 2(z^{2} + 7 z +3)

Step-by-step explanation:

We have the following expression:

z+(z+6)z+(z+6)z+(z+6)

Let's solve it:

z+z^{2}+6z+z^{2}+6z+z+6

We have this result:

2z^{2} + 14 z +6

However if we apply coomon factor 2, we will have a simplified result:

2(z^{2} + 7 z +3)
