Answer:
x6 − x3 − 20 = (x3)2 − x3 − 20 = (x3 + 4)(x3 − 5)
Step-by-step explanation:
In this trinomial, the exponent of the first term, 6, is double the exponent in the second term, 3. And, the third term contains no variables. So, we can factor the expression as we would a quadratic, but treating x3 as if it were x:
Answer:
(x³ - 5)(x³ + 4)
Step-by-step explanation:
Consider the factors of the constant term (- 20) which sum to give the coefficient of the x³ term (- 1)
The factors are - 5 and + 4, since
- 5 × 4 = - 20 and - 5 + 4 = - 1, hence
- x³ - 20 = (x³ - 5)(x³ + 4)
Y = 4x - 2
Answer:
Step-by-step explanation:
first flip
now add 2 to each side
now
divide by 4
so
A)74.2
B)74.9
C)75.1
D) 75.4
Answer:
C
Step-by-step explanation:
The mean is the average so you must add them all up and divide them by the amount of numbers there are.
Answer:
(C) 75.1
Step-by-step explanation:
Add all the numbers then divide by numbers of numbers their are
91+91+91+97+65+37+41+76+ 87= 676
676/9= 75.1111111111 and it goes on forever
