Answer:
17
Step-by-step explanation:
Let x represent the smaller integer. Then we have ...
(x +1)² +(x +2)² = 40x +5
2x² +6x +5 = 40x +5
x² -17x = 0 . . . . . subtract (40x+5), divide by 2
x(x -17) = 0 . . . . . factor
The solution of interest is x = 17.
The smaller integer is 17.

Answer:
Statements (1) and (2) TOGETHER are NOT sufficient.
Step-by-step explanation:
If y ≠ 1, is x = 1 ?
(1)
= 1
(2) y = 1 – x
The two statements are not sufficient to assert this claim. The statement If y ≠ 1, is x = 1 only holds in the two statements if y=0 as seen below.
(1)
= 1

x=1
(2) y = 1 – x
0=1-x
x=1
Every other value of y fails the condition. So a sufficient statement would have been:
If y ≠ 1, and y=0, is x = 1 ?
(1)
= 1
(2) y = 1 – x
