Answer:
Step-by-step explanation:
Since the sale price is always less than the original, we take the original and subtract from it the percent off to give us the sale price. Putting that into equation form:
s = r - .10r
which says, in words, that the sale price is equal to the regular price minus 10% of the regular price.
7 times 7 = 49. Perfect square.
3 times 3 = 9. Perfect square.
15 times 15 = 225. Again, a perfect square.
The other two, 17 and 143, come out as decimals. So, your final answer would be 49, 7 and 225. Hope it helps! If you could vote my answer as the brainiest, that would be awesome! :)
X=5,2
x^2-6x+8=x-2
x^2-7x+10
(factor)
(what multiplies to be 10 and adds to be -7)
(x-5)(x-2)
(put each equation equal to zero)
0=x-5 x-2=0
x=5,2
