<span>(4 - 8i)(2 - 7i)
Use the method FOIL
8 - 28i - 16i + 56i^2
Subtract 16i from -28i
Final Answer: 8 - 44i + 56i^2</span>
Answer:
Step-by-step explanation:
first, 4l=2 x π x radius............................ eqn 1
next, find the value for the radius, r using
Area of a circle=πx radius squared
61.6=3.142 x r x r
61.6÷3.142=r x r
r x r= 19.6
r=4.43
then substitute the value of r in eqn 1
4l=2 x 3.142 x 4.43
4L=27.83812
L= 27.83812÷4
L≈6.96
area of a square = L x L
=6.96 x 6.96= 48.43
Answer:
16/77 or about 21%
Step-by-step explanation:
P(G,B) = 8/22 x 12/21 = 16/77 (simplified)
0.848076
^ This is the tenths place.
The number after it is 4, which is less than 5. So we round down to 0.8.
I think it’s 42 because 36+6 is 42
