Answer:
Step-by-step explanation:
I assume the denominator is (4-√3)
Multiple both top and bottom by (4+√3)
[5(4+√3)]/[(4-√3)(4+√3)]
=[20+5√3]/[4²-(√3)²]
=[20+5√3]/13
Add: (3x2 - 5x + 6) + (9 - 8x - 4x2)
The givens should be arranged first before we can start answering.
3x2 - 5x + 6 plus
-4x2 - 8x + 9
= -x2 - 13x +15
Therefore, the answer to the question is E) -x2 - 13x +15
The slope of the given line is 2.
The slope of the line perpendicular to the given line is the negative reciprocal of 2 or -1/2.
Answer: -1/2
18. The shape is only shifted to a different location and orientation but remains the same size so this is congruent.
19 and 20 are both scaled to a different size so they are both similar.
