2(x^2+6x+9) = 2(x+3)^2
So after divided by (x+3), answer will be:
2(x+3)
Answer:
93
Step-by-step explanation:
All the angles in a triangle add up to 180 degrees.
52 + 35 + x = 180
87 + x = 180
x = 93 degrees
A point has a positive x and y coordinate- answer is Quadrant I
1. 1 1/3
2. 10 7/8
3. 4 7/15
4. 4/7
I hope this helps. :)
Answer:
BC= 20 units
Step-by-step explanation:
Since ∆ ABC is an equilateral triangle, all the sides are equal in length.
AC= BC
=>-y+23= 6y+2
=>-y-6y= 2-23
=>-7y= -21
=>y= 21/7
=>y= 3
BC = 6y+2 = 6(3)+2 = 18+2 = 20 units
