If x = -3 is a zero of f(x), which of the following must be true?

Mathematics
1 answer:
Alla [95]3 years ago
4 0

Answer: B

Step-by-step explanation: You make the values in the parentheses equal to zero.

(X + 3) = 0

X = -3

A is wrong because the root would be 3, not negative 3. C is wrong because 3 isn’t guaranteed to be a root. D is wrong because -3 is a real solution.

Three times the square of a nonzero number is equal to twelve times the number.
dedylja [7]
Well if you write the statement as an equation then that will get you

3*x^2 = 12x

Now we just solve.  You can divide both sides by 3x and that gives you x = 4

Find the sum of the first 21 terms of the sequence 5, 9, 13, 17, 21, ... a. 945 c. 947 b. 944 d. 946
Alborosie
See how the arithmetic sequence is made:
5, 5+4=9, 9+4=13, 13+4=17, ...
So the 21th term will be:
5( first term)+20( n-1 term)•4= 85
And the sum of the first 21 is :
21(5+85)/2= 21•45= 945
