Answer:
x = 65 degrees
Step-by-step explanation:
the supplemental angle of 127 is 53 because 180 - 127 = 53
62 + 53 + x = 180
x = 180 - 62 - 53
x = 65 degrees
So the equation to remember is ax^2+bx+c so since the equation is x^2-4x-21 then a is x^2 and b is -4x
Answer:
The third one as it's cubic
Least common multiple of 6 and 14 is 42
Answer:
a=7.6
Step-by-step explanation:
Since the perimeter is the length of the circumference, P=2a+2b=2(a+b)
We know b and P and if we do the math we get the answer
