12x^3 + 15x^2  + 4x^2 + 5x - 4x - 5           use the Distributive    

                                                                  Property* to  multiply

                                                                  each term by each other

Vilka [71]

what you do is take 5 away from 3. No! Borrow 1 Whole (9) and makes it 9 13/8 - 8 5/8 then subtract the 2 fractions

\frac{13}{8}  -  \frac{5}{8} ...

and that is

\frac{8}{8}

then convert that into 1 whole. Now add the whole to the 9 and thats 10. Now, subtract the 2 whole numbers. 10-8=2 so the answer is 2

pogonyaev

Answer: C) $480  


Step-by-step explanation:

Given: Jose invested $5000 into a fund with an interest rate of 4.8%.

Therefore, Principal amount (P)$5000

Rate of interest = 4.8%

In decimal rate of interest(r)=0.048

Time (t)= 2 years

We know that the simple interest is given by

S.I.=Prt\\\Rightarrow\ S.I.=5000\times0.048\times2\\\Rightarrow\ S.I.=\$480

Hence, the interest after 2 years = $480
