What is 4x + 3i * 7x +4i
1 answer:
If you're multiplying these terms with imaginary parts, do it just like you would any binomial multiplication. (4x+3i)(7x+4i). FOIL-ing that out we get, before simplification, 
. There are 2 things to simplify here: Combining like terms and then dealing with the squared i. 
is equal to -1, so 12(-1) = -12. Then we will combine the ix terms and in the end we will have

Answer:
Find out the what is the price of oranges this week .
To prove
As given
last week the price of oranges at the farmers market was $1.75 per pound.
This week a price has decreased by 20% .
20% is written in the decimal form
= 0.20
Decreased in the price = 0.20 × 1.75
= $0.35
The price of oranges this week = Price of orange at last week - Decreased in the price
= $1.75 - $0.35
= $ 1.4
Therefore the price of oranges this week is $1.4 .
Answer:
Option C.
Step-by-step explanation:
Let as consider parallel lines r and s are cut by transversal q. On line s where it intersects with line q, the uppercase left angle is 125 degrees and the bottom right angle is d degrees.
We need to find the value of d.
If a tranversal line intersect two parallel lines, then the alternate exterior angles are equal.
Uppercase left angle and bottom right angle are alternate exterior angles. So we can say that
d = 125°
Therefore, the correct option is C.
