Answer: 46-3i
Step-by-step explanation: Use the FOIL method, (a+b)(c+d)=ac+ad+bc+bd. Collect like terms then simplify.
(6+7i)(3−4i)
18−24i+21i+28
(18+28)+(−24i+21i)
46-3i

Given:
The ratio of the area between a small square of land and a large square
of land is 3: 7.
Total area of the two squares of land (in sq. meter) is 4000.
Required:
The area of each square of land.
Answer:
We have the ratio of the area between a small square of land and a large square of land is 3: 7.
Let

be the area of the square of land.
Then their ratio is given by,

Also given that the total area of the two squares of land (in sq.meter) is
4,000.
The area of
Therefore,

Therefore,the area of small square (in sq. meter) is,

and the area of large square (in sq. meter) is,

Final Answer:
The area of small and large square respectively (in sq. meter) is,1200 and 2800.

Answer:
Table W represents a function
Step-by-step explanation:
Mathematically, for us to have a function , no two y-values can take a single x value
But it is possible that two x-values have a single y value
So let us make a selection from the table
We have the correct option as;
W
Answer:
2/5
Step-by-step explanation:
Slope can be found with rise over run. So looking at the graph, the line rises 2 units and runs 5 units to the right. Therefore, the slope should be 2/5.
