Step-by-step explanation:
she took the 2X and substract 4X-2X
the answer will be 2X=402
A= 3.14* 12^2
= 3.14* 144
= 452.16cm^2

Answer:the answer should be c
Step-by-step explanation:So, the 11 is an exponent. That means that the problem can be written as 11 x 7/4 so it should be c.
The unit rate will be in revolutions per second. That means divide number of revolutions by number of seconds.
first convert from mixed fraction.
6 2/5 = 32/5 revolutions
2 2/3 = 8/3 seconds
32/5 ÷ 8/3
flip multiply
32/5 × 3/8 = 12/5 revolutions per second
12/5 = 2 2/5 revolutions per second
