Answer:
Step-by-step explanation:
Explanation:
Use the extended form of the perfect square trinomial identity:
a4 + 2a2b2 + b4 = (a2 + b2)2.
a2 = x2 and b2 = 32
x4 + 18x2 + 81 = (x2)2 + (2)(x2)(32) + (32)2
= (x2)2 + 2(32)x2 + (32)2
= (x2 + 32)2
= (x2 + 9)2
27.
18 divided by 2 = 9
40 divided by 2 = 20
20 x 3 = 60 min = 1 hour
9 x 3 = 27.
so 27 problems finished in 1 hour.
E, the rest are all linear functions
Answer:
8.25 yards
Step-by-step explanation:
12.21 ÷ 1.48 = 8.25 yards
Yes because whatever x is it is less than 2 which means 0 or 1 or in negative so if you minus 0 or 1 from 2 you will get a negative answer
