Answer: n⁴+10n²x+25x²
Step-by-step explanation:
I don;t know how I can use the binomial squares pattern on Brainly, but I can definitely guide you through the problem.
(n²+5x)² [rewrite this from the squared]
(n²+5x)(n²+5x) [use FOIL to expand]
n⁴+5n²x+5n²x+25x² [combine like terms]
n⁴+10n²x+25x²
3t shirts cost $18
1 shirt will cost 18/3t = 6/t
7t shirts will then cost = (6/t)*7t = 42
7t shirts will cost $42.00
Answer:
A.1/3
Step-by-step explanation:
1 Pick two points on the line and determine their coordinates.
2 Determine the difference in y-coordinates of these two points (rise).
3 Determine the difference in x-coordinates for these two points (run).
4 Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).
What is the name of that type of math
Answer:
C
Step-by-step explanation:
Chaz is 3 years younger than 4 times the age of his nephew
n is the age of the nephew.
4 times the age of the nephew.
So you now have 4n.
Now you gotta subtract 3 from 4n which gets you to choice C.
4n - 3
