4x - 12
You can get this by switch the f(x) and the x and then solving for the new f(x)
Answer is c.
t = 0.5(d+h)
multiply both sides by 2 to cancel out the 0.5.
2t = d+h
2t - d = h
Answer:
x = 7.3
Step-by-step explanation:
area = base × height / 2

Step-by-step explanation:
√a^4 is the same as:
√a × √a × √a × √a
group them as 2 pairs of
(√a × √a) × (√a × √a)
which makes
a × a
which is the same as
