Median equals 25.5 and mean equals 22... I think
Answer: -5x+3x²+5
Step-by-step explanation:
(-2x+4x²+5)-(x²+3x)
=-2x+4x²+5-x²-3x
=-2x-3x+4x²-x²+5
=-5x+3x²+5
=3x²-5x+5 (if you are required to write in standard form)
Answer:
-5.5
Step-by-step explanation:
You just need to subtract the two I'm pretty sure
Answer:
34
Step-by-step explanation:
Of I is the incenter then : AI, BI, and CI would be equal
if lengths are equal we can make an equation to solve the length of BI
AI = BI ➡ 3x+7 = 5x-11 ➡ 2x = 18 ➡ x = 9
replace x with 9
5x-11 ➡ 5×9-11 = 34
