T² -1 =(t)² - (1)² = (t + 1) (t - 1)
----------------------------
Answer: (t + 1) (t - 1)
----------------------------
2/5 x 60 = 24
2/5 x (4x - 1) = x+5
8x - 2 = 5x + 25
3x = 27
x = 9
The value of x is 9
Answer:
The population of California is about 5 times the population of south Dakota
Step-by-step explanation:
Let
x ------> the population of California
y -----> the population of south Dakota
we have
x=4,000,000 people
y=800,000 people
Divide the population of California by the population of south Dakota, to find out how many times the population of South Dakota is the population of California
so
x/y
substitute
4,000,000/800,000=5
therefore
The population of California is about 5 times the population of south Dakota
I dont think so but to justify quads means four and the is no sign of x to the fourth power or y to the fourth power ect.
C)
the answer should be 24a^-1b^10
