Answer:
x = +5
Step-by-step explanation:
The triangles ADB and BDC are similar. Thus it is possible to write an equation of ratios and solve it for x:
x 10
----- = -------
10 4x
Cross-multipying, we get:
4x^2 = 100, which yields x = +5
Dees nuts because it’s spleens it but yea
Answer:
15 dollars
Step-by-step explanation:
I believe this is it
(y² - 3)(y⁴ - 6y² + 9)
y²(y⁴ - 6y² + 9) - 3(y⁴ - 6y² + 9)
y².y⁴ - y².6y² + y².9 -3.y⁴ - 3.(-6y²) -3.( 9)
y⁶ - 6y⁴ + 9y² - 3y⁴ + 18y² -27
y⁶ - 6y⁴- 3y⁴ + 9y² + 18y² - 27
y⁶ - 9y⁴ + 27y² - 27
I hope this helps.
The ticket price was decreased by 8.75-6=2.75$
to know the percentage of decrease:
percentage=(fraction of decrease/total price) x 100
percentage = (2.75/8.75) x 100
= 31.4%
