Step-by-step explanation:










The other factor is:

Incase it helps to have a slightly different approach, the way we learnt it is:
y2 - 10y + 16 = 0
When these are factorised, the brackets you have will need to expand to equal the above.
You need to find 2 numbers that multiply together to make the end number, c, and those 2 numbers must also add together to made the middle number, b.
So for this case, those two numbers would be -2 and -8.
Then these go into the brackets,
(y - 2) (y - 8) = 0
This can then be proven to be correct via expansion,
y x y = y2
y x -8 = -8y
-2 x y = -2y
-2 x -8 = 16
(y2) + (-8y) + (-2y) + (16) = 0
y2 - 8y - 2y + 16 = 0
y2 - 10y + 16 = 0
Hope this helps a little?

Answer:
Option C is correct
Step-by-step explanation:
5c – 20 ≤ 15c + 10
<=> 5c - 15c ≤ 20 + 10
<=>-10c ≤ 30
<=> c ≥ -3
Hope this helps!
Let the number be x.
x/3 + 12 = 46
Subtract 12 from both sides and you will get:
x/3 = 34
Multiply both sides by 3:
x = 102
