Step-by-step explanation:
2x^2-2x-12
This has solutions of x=3 and x= -2
Answer:
5 cats
Step-by-step explanation:
d/c = 5/1
d = 25 Substitute in the proportion
25/c = 5/1 Multiply both sides by c
25 = 5c/1
25 = 5c Divide each side by 5
c = 5
There are five cats.
(-2x + 4y)(3x - 7y) = -6x^2 - 28y^2 + 12yx
The new height of the water is = 9.34 inches (approx)
Step-by-step explanation:
Given, a rectangular container measuring 20 inches long by 16 inches wide by 12 inches tall is filled to its brim with water.
Let the new height of water level be x inches.
The volume of the container = (20×16×12) cubic inches
=3840 cubic inches
According to the problem,
3840 - (20×16×x) = 850
⇔3840 -320x = 850
⇔-320x =850-3840
⇔-320 x = -2990

⇔x = 9.34 inches
The new height of the water is = 9.34 inches (approx)
