Answer:
Step-by-step explanation:
9x2 + 6x. = 3x(3x + 2). Answer: 3x(3x + 2). 2. Simplify: (-7x2 - 3x) - (4x2 - x) Solution: ... -2(2x + 5)<u> </u><u><em>Answer: -2(2x + 5) 8. Simplify:(8+4x)/4x. </em></u>Solution: (8+4x)/4x = 4(2 + x)/4x ... Compare the above equation 3x2 – 5x + 1 =0 with ax2 + bx + c = 0
hope this helps. : )

3)B
4)A
Step-by-step explanation:
1) Circle
Solve for area
A≈28.27cm²
d=Diameter 6cm
Using the formulas
A=πr2
d=2r
Solving for A
A=1
4πd2=1
4·π·62≈28.27433cm²
