Answer:
x^2 -10x - 15 = 0
(don't know how far you want me to go)
Step-by-step explanation:
(x - 5)^2 = 40
(expand the brackets)
(x - 5)(x - 5) = 40
x^2 -5x -5x + 25 = 40
x^2 -10x + 25 = 40
x^2 -10x - 15 = 0
<span>Use the explicit formula a</span>↓n=a↓1+(n-1)d to find the 1000th term of the sequence below. <span>24,31,38,45,52,..
a(1000) = 24 + 999*7 = 7017 Thus your answer is A</span>
