The number is 20. 20+10 (half of 20) + 4 (a fifth of 20) = 34
There are two answers to this question
the first possible answer is 5, 6, and 7 and the second possible answer is -4, -3, and -2
Step-by-step explanation:
let the three numbers be (x-1), x, and (x+1)
the product of the smallest and largest number is 17 more than 3 times the middle number, or
(x-1)(x+1) = 3x+17, or
x^2-1 = 3+17, or
x^2-3x-18 = 0
(x-6)(x+3) = 0
So x = 6 or -3
Then just subtract one and add one to get the other integers. the three numbers are 5, 6, and 7 or -4, -3, and -2
3p < 12
p < 4
and
-3p < 12
p > -4
answer
-4< p < 4
It's C. third one
The number (variable n) would be 7. work is in the pic
