4-1/2x=10
-1/2x=6
3
so your answer would be B
hope that helps
Answer:
3(x +3)
Step-by-step explanation:
factored by grouping
well, it's isosceles so use base angles theorem
the top angle is also x
90 + 2x = 180
subtract 90 from both sides
2x = 90
divide both sides by 2
x = 45 degrees
It must be true that one of the numbers is negative. Hope that helps!!
