Step-by-step explanation:
a. 5x² - 80
b. 5(x² + 4x - 4x -16)
5(x² - 16)
5x² - 80
c. 5x² - 20x + 20x - 80
5x² - 80
d. 5x² - 11
D doesn't belong because 5x² - 11 is not the answer to A, B, or C.
Answer:
Step-by-step explanation:
Let's solve your equation step-by-step.
3x(x−2)=0
Step 1: Simplify both sides of the equation.
3×2−6x=0
For this equation: a=3, b=-6, c=0
3×2+(−6x)+0=0
Step 2: Use quadratic formula with a=3, b=-6, c=0.
x=2 or x=0
hope it helps other wise I am sorry
The correct answer is 556
Step-by-step explanation:the mean is 16.75 why because 2+4+6+8+10+12 is 42 divide that by 6 and you get 16.75
Answer:the 57th term is 78
Step-by-step explanation:
The sequence is an arithmetic sequence. The formula for determining the nth term of an arithmetic sequence is expressed as
Tn = a + (n - 1)d
Where
a represents the first term of the sequence.
d represents the common difference.
n represents the number of terms in the sequence.
From the information given,
a = - 6
d =3/2
n = 57
We want to determine the value if the 57th term, T57. Therefore,
T57 = - 6 + (57 - 1) ×3/2
T57 = - 6 + 56 × 3/2 = - 6 + 84
T57 = 78
