feet
Step-by-step explanation:
Well the perimeter is the sum of all sides that means
P= lenght + width + lenght + width
P=2(lenght + width)
so
Answer:
<h3>a = 1 and b = 7</h3>
Step-by-step explanation:
Given the complex expression, (3 + i)(1+2i) we are to expand it in the form a+bi as shown;
(3 + i)(1+2i)
= 3(1)+3(2i)+1(i)+i(2i)
= 3 + 6i + i + 2i²
= 3 + 71 + 2i²
According to complex notation i² = -1
;Substitute
= 3+7i+2(-1)
= 3 + 7i - 2
= 1 + 7i
Comparing 1+7i with a + bi
a = 1 and b = 7
