Answer:
x = -1, 1, 9
Step-by-step explanation:
You want x such that f(x) = g(x). Subtracting g(x) from both sides of this equation lets us rewrite it as ...
f(x) -g(x) = 0
x³ -9x² -(x -9) = 0
x²(x -9) -1(x -9) = 0 . . . factor the first pair of terms
(x² -1)(x -9) = 0 . . . . . . use the distributive property
(x -1)(x +1)(x -9) = 0 . . . . factor the difference of squares
Values of x that make these factors zero will make f(x) = g(x):
x = -1, 1, 9 for f(x) = g(x)
No. of pink T-shirts was 342
<h3>How to solve it?</h3>
Given: 24% of the T-shirts were white
Let, total number of T-shirts be x
According to question,
Total no. of white T-shirts =
Total No. of pink T-shirt = + 198
Total No. of red T-shirts = 114
According to the question:
+ 198 + 114 = x
312 = x -
312 =
x =
x = 600
so No. of pink T-shirts :
+198
= 144 + 198
= 342
Hence total No. of pink T-shirts was 342.
