9x - 24 + 4x = -24 + 14x - x
13x - 24 = 13x - 24
0 = 0
Answer is All real numbers
Answer:
It’s C and D I just finished the text and finished with 100% thanks to the person in the comments in the question below
Step-by-step explanation:
(x+5)(x-5)
= x^2 - 5x + 5x - 25
= x^2 - 25
(5x+3)(5x-3)
= 25x^2 - 15x + 15x - 9
= 25x^2 - 9
do you see the pattern? both the coefficient on x and constant multiply together to make a perfect square and the middle term, also known as "b" term cancels out leaving a binomial
Answer:
n=5/4 or n=-1/4
Step-by-step explanation:
16n^2 - 10n-5=6n
16n^2-16n-5=0
(4n)^2-2.4n.2+2^2 = 2^2 + 5
(4n- 2)^2=9
4n-2 = 3 or 4n-2=-3
4n=5 or 4n=-1
n=5/4 or n = - 1/4
