Answer:
D
Step-by-step explanation:
The question states you need a square. That means whatever you do, must leave a square number like 49 or 64
If you add 6 or 7 to 56 you do not get 64 A and C are both wrong.
If you subtract 7 from 56 you get 49 which is a perfect square and all 4 sides will equal 7.

Answer: 925 pages
Step-by-step explanation:
From the question, we are told that with a full ink cartridge, a printer can print 2,500 pages but that the printer cartridge is now 37% full.
The best estimate of the number of pages the printer can still print will be calculated as:
= 37% × 2500
= 0.37 × 2500
= 925 pages
F(x) = -5x - 4
g(x) = 6x - 7
f(x) + g(x) = (-5x-4) + (6x-7)
f(x) + g(x) = x - 11
