Answer:
Step-by-step explanation:
radius 70/2=35 cm
circumference=2πr=2π×35=70π cm
time taken to complete one revolution=0.8 s
or distance covered in 0.8 s=70π
distance covered in 1 s=70π/0.8=700 π/8=175 π/2 s=87.5 π≈274.9 cm
speed=274.9 cm/s=2.749 m/s
5 times sign 2+7=17 you have to times 5 and 2 and when u get the answer add it with seven

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. : )
