Step-by-step explanation:
hello :
5x²(2/5-x) = 5(2/5)x²-5x^3 = -5x^3+2x² is not a trinomial
Answer: B. b + v = 67; b = 2v + 4
Step-by-step explanation: since both the basketball and the volleyball cost 67, we can represent that as b + v = 67.
If you multiplied the cost of the volleyball by 2 and then added 4, you would get the cost of the basketball:
b = 2v + 4

Answer:
y = 2x^2 +1
Step-by-step explanation:
This is a parabola so it is in the form
y = a( x-h) ^2 + k
where ( h,k) is the vertex which is at ( 0,1)
y = a (x - 0)^2 + 1
y = ax^2 +1
Pick another point on the graph to determine a
(1,3)
3 = a(1)^2 +1
Subtract 1 from each side
3-1 = a(1)
2 =a
y = 2x^2 +1
Answer: 1/20 (fraction) or 0.05 (decimal)
Step-by-step explanation:
first i like to make them a decimal so its easier.
1/4 = 0.25
1/5 = 0.2
multiply 0.25 and 0.2 = 0.05
make 0.05 a fraction
1/20
simplify. (it's already in its simplest form)
the answer is 1/20 as a fraction or 0.05 as a decimal.
(i dont know which one ur teacher wants u to do fraction or decimal?)
18 x 20 = 360
360 / 20 = 18
So 18 is the answer
