Answer:
x = √149 km
Step-by-step explanation:
Pythagorean theorem
x^2 = 10^2 + 7^2
x^2 = 100 + 49
x^2 = 149
x = √149
49–2ax –a^2–x^2
Extract the negative sign
= 49 - (a^2 +2ax +x^2)
Factor using a^2 + 2ab + b^2 = (a+b)^2
= 49 - (a+x)^2
Factor using a^2 - b^2 = (a-b)(a+b)
= ( 7- (a + x)) * (7 + (a + x))
= ( 7- a - x) * (7 + a + x)
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
