Answer:
47.13
Step-by-step explanation:
Circumfrence= 2 x pi x Radius
2 x 3.142 x 7.5 =47.13
Circumference=2pir=<span>2∗3.14∗5.1</span><span>=30.028=30.03.</span>
C is the answer because there is no variable for X which without it would make a horizontal line.
Factor out the GCF first
3(2x² - x - 10)
3(2x - 5)(x + 2)
