I’ll assume the question is asking us to factor the above polynomial:
5x^2 + 10x - 45
Factor out a 5:
5(x^2 + 2x - 9)
This appears to be an irreducible quadratic polynomial, so let’s leave it alone.
5x^2 + 10x - 45 = 5(x^2 + 2x - 9)

Answer:
BC = 35
Step-by-step explanation:
The sum of the segments is the overall length.
AB +BC = AC
(2x +6) + (6x +5) = 51 . . . . substitute given values
8x +11 = 51 . . . . . . . . . . . . . collect terms
8x = 40 . . . . . . . subtract 11
x = 5 . . . . . . . . . divide by 8
BC = 6x+5 = 6(5) +5 . . . . . . . . use the value of x to find BC
BC = 35
Answer:
-3<y<3 The filled in dot means 3 is greater than or equal to.
Answer:
C
Step-by-step explanation:
The range is the values of y from the vertex upwards
The vertex = (- 2, - 4) → y = - 4
The range is from - 4 upwards in the direction of the parabola, that is
range is [ - 4, ∞ )
