Answer:
-3(x + 2)(5x - 3)
Step-by-step explanation:
-15x² – 21x + 18
-3(5x² + 7x - 6)
-3[5x² + 10x - 3x - 6]
-3[5x(x + 2) - 3(x + 2)]
-3(x + 2)(5x - 3)
To solve, set an equation:
472=0.8x
Divide both sides by 0.8
472/0.8=0.8x/0.8
x=590
Answer: The original price was $590
Step-by-step explanation:
180= 90+30+20x 90+30=120 180-120= 60
20x=60 x=3
Answer:

2. corrseponding angles are equal
Answer:
$86.60
Step-by-step explanation:
1. Subtract 8-3=5
2. Multiply 3*8.95=$26.85
3. Multiply 5*11.95=$59.75
4. Add $26.85+$59.75=$86.60
