the perimeter of a triangle is represented by 3x² +8x-9. Two of its sides are represented by (x²+11x+5) and (-2x²-4x+2) What expression would represented the third side​

The third side has a length of 4x² + x - 16

Step-by-step explanation:

We can solve this by taking the value given for the perimeter, and subtracting the values of the other two sides:

3x² + 8x - 9 - (x² + 11x + 5) - (-2x² - 4x + 2)

= 3x² + 8x - 9 - x² - 11x - 5 + 2x² + 4x - 2

= (3 - 1 + 2)x² + (8 - 11 + 4)x - (9 + 5 + 2)

= 4x² + x - 16

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
