Answer:
(2a+1)(2a-5)
Step-by-step explanation:
30-60-90
hyp = 2 * short leg
Long log = √(3) * short leg
long leg = 25√3
The correct answer is D.
If you look at the equation you can see that the line crosses at the points
(1,5) and (-2, -4). Use this set of ordered pairs to find the slope.
(-4-5)/(-2-1) = (-9/-3) = 3
The use the point-slope formula and fill in the ordered pair (1,5) with the slope.
y - 5 = 3( x - 1)
The circumference of any circle is (pi) x (the diameter of the circle).
The problem gives you both numbers, so all you have to do is multiply them.
Circumference = (pi) x (diameter) = (3.14) x (21cm) = <span>65.94 cm .</span>
