If the simple interest on $7,000 for 2 years is 980, then what is the interest rate?

7%

Step-by-step explanation:

since the formula says si=ptr/100

so we have to separate r which gives us r =(i ×100)/(p×t)

now putting the values (980×100)/(7000×2)

=7

therefore the rate of interest is 7%

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )
