4y-y is NOT equivalent to 4.
4 is multiplied by 'y', and then 'y' is subtracted from that equation. Even if y=1, your equation would look like 4x1-1=3.
Hope that made sense:)
Step-by-step explanation:
This is the answer for I)
Just use Pythagorean theorem formula to the tye hypotenuse.
Answer:
28 strokes
Step-by-step explanation:
The computation is shown below:
It is given that the 42 strokes are required to fill up the 3 by 5th
So for completing the line, the number of additional strokes required is
But before the total strokes required is
= 42 × 5 ÷ 3
= 70
This represent the total
so, the additional strokes is
= 70 - 42
= 28 strokes
20 now give brainly
if that is not it its -20
