Step-by-step explanation:
Answer:
(3 - 5i)/ (8+2i)
multiply numerator and denominator by (8-2i) (conjugate of (8+2i))
(3 - 5i) x (8-2i)/ (8+2i)x(8-2i)
24 - 6i -40i + (5i)x(2i) / 64 -16i +16i -(2i)(2i)
24 - 46i + 10i^2 / 64 -4i^2
24 - 46i +10(-1) / 64 -4(-1)
Note:
i =sqrt(-1)
Get both side power of 2
i ^2=(sqrt(-1))^2
= -1
24 - 46i -10 / 64 +4
14 - 46i / 68
simplify;
14/68 - 46i/68
7/34 - 23i/34
Step-by-step explanation:
The area of a triangle in determined by the formula:
where b is the base of the triangle and h is it's height
You just have to replace the b and h with their values in the formula (b=9.9ft and h=5.5ft)
The answer is 27.225 ft^2
Answer:
c: 5 x 3/5
Step-by-step explanation:
so the is 15 blocks shaded on the 25 grid
so i would work out each fraction answer and find which one makes 15/25
5 x 5/3 = 25/25
3/5 + 3/5 + 3/5 + 3/5 + 3/5 + 3/5 = 21/5
5 x 3/5 = 15/25
hope this helps :)
if the answer is wrong plz comment and i will fix thanks :)
