Hi friend,
This is a perfect square trinomial.
It can be recognised because it is of the form:
a^2−2ab+b^2=(a−b)^2
with a=3x and b=4
9x2−24x+16=(3x)2−(2⋅(3x)⋅4)+42
=(3x−4)2
C because there are 60 seconds in a minute so if you multiply 600 x 60 you get 36000
Answer:x=7/5
Step-by-step explanation:
Y=6. you would replace x with 7 in the equation.
6(7) = 7y
42=7y
6=y
Answer:
2.2
Step-by-step explanation:
