Step-by-step explanation:
(14-2) - 3:(2.3)-22= 12- 1.3-22= -11.3
Answer:
6.28 m
Step-by-step explanation:
If a wheel travels with one full revolution, it would have travelled the circumference's distance from it's starting point.
The circumference of a circle is 
Let's assume 
is 3.14 and solve for the equation.
Hope this helped!
(x-3)² ⇒ (x-3)(x-3)
(x-3)(x-3) = x(x-3) -3(x-3) ⇒ x² - 3x - 3x + 9 ⇒ x² - 6x + 9
The 3rd option is the correct answer. x² - 6x + 9
Answer:
4th option
Step-by-step explanation:
The relationship is linear,
putting the value of x in the right side of the equation of option 4, you'll get the value of the left side
putting, x=1
y+4=-1/2(x-1)
y=-1/2(1-1)-4
y=-4
putting, x=7
y+4=-1/2(7-1)
y=-1/2(6)-4
y=-6/2-4
y=-3-4
y=-7
