Answer:
D; it was bought for $5,487.36
Step-by-step explanation:
Let the investment amount be $x
We use the formula for simple interest to get the interest
(2112.64-x) = (x * 5.5 * 7)/100
211264-100x = 38.5x
138.5x = 211264
x = 211264/138.5
x = 5,847.36
Answer:
7a^6b
Step-by-step explanation:
Using the pascal triangle to do this binomial expansion, we find out that the coefficient is 7. The a variables start at the power to which you are expanding and reduce by 1 for every consecutive term. The b variables start at the power of 0 and increase by 1 for every consecutive term. Using this information, we find out that the second term in the binomial expansion (a+b)^7 is 7a^6b
Note that the power of b in the second term is b^1 which is the same as b
(4+3)(7-4) if you want the products to multiply each other
4+3(7-4) if you want to use the distributive property and simply have 3 multiplied but the simplification of 7-4 which is 3
