Hello there!

The formula to find the area of a trapezoid is:
A = \frac{a+b}{2} h

Since we have everything, we just plug them in :)

A = \frac{3x+3x+4}{2} (x+2)

A = (3x+3x+4)/2 (x) + (3x+3x+4)/2 (2)

A= <span><span><span><span>3x^2</span>+<span>2x</span></span>+<span>6x</span></span>+<span>4

A = </span></span><span>3x^2+8x+4

The correct answer is option A

I hope I helped!
Please feel free to ask me any additional questions about the answer.

9+19 - 12 + 12 + 12323 - 39
Alexxandr [17]

Answer : 12312

Step-by-step explanation : According to BODMAS, Addition (+) comes first

Hence --  9 + 19 + 12 + 12323 = 12363

               12363 - 12 - 39  = 12363 - 51

                                          = 12312

Find the opposite of 1/3 and of -7/12
dimaraw [331]
Opposite number is the same number with the opposite sign:

So the opposite of \frac{1}{3} is -\frac{1}{3}, since the original number is positive

opposite of - \frac{7}{12} is \frac{7}{12}, since the original number is negative

HELP ME OUT PLEASE!!!
ANTONII [103]

Answer:

D) y= 4x - 1

Step-by-step explanation:

We are basically trying to see which of the equations provided are true on both sides of the equal sign when you plug in the x and y values.

Let's start!

Choice A:

  plug in 0 for x and -1 for y

-1 = 4(0)

And you are left with...

-1 = 0

This equation is false! Therefore it does not match the function in the table

Choice B:

   plug in the values again

-1 = 0 + 1

-1 = 1

False!

Choice C:

-1 = 0 + 5

-1 = 5

False!

Lastly...Choice D:

-1 = 4(0) -1

Multiply 4 and 0 which is 0, so you are left with...

-1 = -1

This equation is true!!

So your answer is D

Hope this helps :D
