Mathematics
1 answer:

Area = Length x width.

30 = w x 3w +1

Simplify:

3w^2 + w = 30

Subtract 30 from both sides:

3w^2 + w -30 =0

Factor

(w-3)(3w+10) = 0

Solve for the w's:

w = 3 and x = -3 1/3

Since the number cant be negative w = 3

The width = 3 cm.

Suppose you & your friends are going to the movies.The amount of money you spend for tickets varies directly with the number
mojhsa [17]
This is the equation you need to use: y = kx
So, let's put it this way:
y can be the total amount of money you spend (so $48), and x the number of people (6)

y=kx
48=k*6
k = 48/6
k = 8

The constant variation, and the price of one ticket is 8.

Find the area. Please help

charle [14.2K]
The answer is a, this is because 5(2+4) is the same as multiplying 5 by 6 to get 30. The reason we do this is because the length of the entire side is the sum of the bottom numbers
