x² - 80 = 0
Add 80
to each side: x² = 80
Square root
each side: x = √80
Look it up: x = + 8.944... (rounded)
and
x = - 8.944... (rounded).
___________________________________
Here's a cleaner solution:
x² - 80 = 0
Add 80
to each side: x² = 80
Square root
each side: x = √80
But 80 = 16 · 5
So √80 = √16 · √5
√16 = 4, so x = 4 √5
This problem can be solve by using
ration and proportion, since you want to enlarge the picture by not distorting
the image, the new dimensions should be in proportion with the old one.
Let x be length of the image
(5/40 = (x/5)
X = 5(5/4)
