Answer:
he needs 20.25 bags of sand and it would cost her 80.79
Step-by-step explanation:
150cm*90cm*15cm=202,500cm^3 this is how much sand she needs to fill it
202,500cm^3/10,000cm^3=20.25 this is how many bags he needs
3.99*20.25=80.79 this is how much it'll cost him for all 20.25 bags

It is not possible if so it wouldn’t be iscosceles
Answer:
2kx+4y=20 ⇒ kx+2y=10
3x+6y=30 ⇒ x+2y= 10
k is the coefficient of x, so it is the slope of the line
- when k=1, both equations will be same, then there are many solutions
- when k=0 there is one solution
- when k is anything different, then the lines will be parallel, so no solutions
Answer:
<em>4x^3(x^2 - 5)</em>
Step-by-step explanation:
First, try to factor a common factor.
GCF of 4 and -20 is 4.
GCF of x^5 and x^3 is x^3.
Factor out 4x^3.
4x^5 - 20x^3 =
= 4x^3(x^2 - 5)
