The expression would be d + 3.
You're raising $3 in every sweaters cost so d is the cost of the sweater and you add 3 to raise $3 in the price.
Hope this helps :)
Find a power series representation for the function. Determine the interval of convergence. (Give your power series representation centered at x
The expression that is equivalent to the complex number 10 + 3i is (4+7i)-2i(2+3i)
<h3>Complex numbers</h3>
Complex numbers are square root of negative numbers. They are expressed as a + bi
Using the expression
(4+7i)-2i(2+3i)
Expand
4 + 7i - 4i -2i(3i)
4 + 3i - 2(-3)
4 + 6 + 3i
10 + 3i
Hence the expression that is equivalent to the complex number 10 + 3i is (4+7i)-2i(2+3i)
