Answer: B. -2x^4y^3
Step-by-step explanation:
Multiply the variables by each other.
-2x^3 * x = -2x^4
y * y^2 = y^3
Answer with Step-by-step explanation:
The number of marbles are as under
3 red , 3 green , 1 Lavender total = 7
Now to select five marbles from a total of 7 marbles such that at least 2 marbles are included are the sum of the following cases:
1) We select 2 exactly 2 red marbles from 3 reds and the remaining 3 marbles are selected from 4 of other colours
Thus
2)We select all the 3 red marbles and the remaining 2 are selected from the remaining 4 marbles
Thus the total number of ways are
waist = 32
hips 40
ratio = 32/40 which reduces to 4/5
Answer:
2/20
Step-by-step explanation:
Answer:
z ∝ x^2
Z = kx^2
when z = 36 and x = 2, substitute into the equation above
i.e, 36 = k x 2^2
36 = 4k
therefore k = 9
so the equation becomes
Z = 9x^2
when x =3
Z = 9 x 3^2
Z = 9 x 9
Z = 81
