It’s c x=5 that what it is lol

Answer:

Step-by-step explanation:

I think it is a ratio problem  since the sides and trapezoid are congruent

It appears to be simplier than I thought.  Each NEW base decreases EVERY equal step up by the SAME amount

The difference between the the bottom base and middle base  is 3.5

21 - 17.5 = 3.5

The difference between the middle base and the top base is the same 3.5 so

17.5 - 3.5 =   14   is the length of the top base 3x + 2

so 3x + 2 = 14

3x = 14 - 2

3x = 12

x = 4   FINAL ANSWER

AB = 3 + x
strojnjashka [21]

Answer:

Option A) 4, 2

Step-by-step explanation:

We are given that quadrilateral ABCD is a  parallelogram with sides:

AB = 3 + x\\DC = 4x\\AD = y + 1\\BC = 2y

Since the opposite sides of a parallelogram are equal, we can write:

AB = DC\\AD=BC

Equating the sides we get,

\Rightarrow 3+x = 4x\\4x-x = 3\\3x = 3\\x = 1\\\Rightarrow y + 1 = 2y\\y = 1

Putting the values of x and y, we get:

AB = 3 + x =4\\DC = 4x =4\\AD = y + 1=2\\BC = 2y=2

Thus, the lengths of the opposite side pairs is 4,2.

Find the area of area of a rectangle with with sides 8 + 2x and 3+ x.
netineya [11]

Answer:

Area = 2x^2 + 14x + 24

Step-by-step explanation:

You could set up an expression (2x + 8) * (x + 3), where you multiply 2x by x, 2x by 3, 8 by x, 8 by 3, and then add them all up. 2x * x  = 2x^2, 2x * 3 = 6x, 8 * x = 8x, and 8 * 3 = 24. 2x^2 + 6x + 8x + 24 = 2x^2 + 14x + 24, so that is your answer.
