Let the smaller number be n:
Therefore 1/2 * n(n+1) = 105
n^2 + n = 210
n^2 + n - 210 =0
Use your preferred method to solve the quadratic, I'll factorise this since this is easy to factorise.
Two numbers':
product gives -210
summation gives 1
Therefore (n+15)(n-14)=0
So the smaller number n is either -15 or 14.
13
Divide 52 by 4 which gives you 13. 13 x 4 = 52
The answer is B.
Explanation:
240-18
= 222
222-18
= 204
204-18
= 186
Answer:
well let's see below.
Step-by-step explanation:
If you're simplifying the fractional form, the answer would be f(x) + x/2 =4.
