First, factor out 5:
5 (x² -x -20)
We need two numbers that add to -1 and multiply to -20. -5 and 4 satisfy this.
5(x-5)(x+4)
G=37
Angle ACD and angle DCB are a linear pair. Meaning they are supplementary.
ACD=90 degrees
180-90=90
90 degrees equals the angle of DCB.
90-53=37
So g=37
Answer:
10 pieces
Step-by-step explanation:
basically you divide 7.5 by .75 which equals 10.
You do that because you are seeing how many 3/4 inch pieces are in 7 and a half inches of ribbon and 7 1/2 = 7.5 and 3/4= .75
