Help pls and ty! What is the area of this trapezoid?
Gnesinka [82]

Answer:

88 units^2

Step-by-step explanation:

The area of a trapezoid is equal to \frac{a+b}{2}h, where a and b are the top and bottom of the trapezoid and h is height.

We can see that a (top) equals 17, and b (bottom) equals 5 + 17 + 5 = 27. Then, the height of the trapezoid is 4.

  • \frac{17+27}{2} * 4
  • \frac{44}{2} * 4
  • 22 * 4
  • 88

Therefore, the answer is 88 units^2.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

stich3 [128]
Given with a polynomial 4X² + 36/4X *1/5X, we can combine terms with the same power. First, let us perform multiplication of the 2nd and 3rd terms such as the given become 4X² + 36/20X². Then, we can reduce 36 and 20 by 4 and the result is 4X² + 9/5X². We can now proceed combining the terms since they have same power and result will be same as below:
