Answer:

12 and 16

Step-by-step explanation:

set up an equation:

since one number is 4 less than the other, let x represent it. for the other number, let x+4 represent it since it's 4 greater than x. set the equation equal to 28 because the sum of the two numbers is 28.

x+x+4=28

now, we solve the equation:

x+x+4=28

2x+4=28

2x=24

x=12.

Since x equals 12, to find the other number, which would be 4 greater than x, we would add:

12+4=16

So, the two numbers are 12 and 16.

The height of a parallelogram is 4 times the base. The base measures 3 1/2 ft find the area off the parallelogram
PilotLPTM [1.2K]

Answer:

Area = 49 ft²

Step-by-step explanation:

The formula for area of a parallelogram is A = bh, where b is the base, and h is the height.  Here, the base is given and the height is 4 times the length of the base

Here b = 3 1/2, and h = 4(3 1/2) = 14      

             3 1/2 becomes 7/2 as an improper fraction,  4(7/2) = 28/2 = 14

So the area is

A = 14(3 1/2)

A = 14(7/2)

A = 98/2

A = 49 ft²
