1. Rationalise the denominator
(20+10i+10i-5)/2^2-i^2
2. Collect like terms
((20-5)+(10i+10i))/2^2-i^2
3. Simplify (20-5)+(10i+10i) to 15+20i
15+20i/2^2-i^2
4. Simplify 2^2 to 4
15+20i/4-i^2
5. Use square rule
15+20i/4-(-1)
6. Simplify brackets
15+20i/4+1
7. Simplify 4+1 to 4
15+20i/5
8. Factor out the common term 5
5(2+4i)/5
9. Cancel 5
3+4i
10. Your final answer
3+4i
Have a nice day ;D
Answer:
Step-by-step explanation:
Let's solve for C.
Step 1: Flip the equation.
Step 2: Add to both sides.
Step 3: Divide both sides by .
Answer:
1/3 x pi x radius squared
1/3 x pi x 0.7225 = 0.7566002307
0.76 to nearest hundredth
Answer:
b is the correct answer.
Step-by-step explanation:
Since the slope is negative, it can't be a or d. The y intercept is 810, so c can't be right. Therefore, b is right.
