Answer:
14a + 20
Step-by-step explanation:
8(a + 2) + 2(2 + 3a)
expand the bracket
8a + (8*2) + (2*2) + (2*3a)
8a + 16 + 4 + 6a
bring like terms together
8a + 6a + 16 + 4
14a + 20
The vertical distance is 5 + 8 = 13
the horizantal distance is 3 +3 = 6
then just do pythag therom
6^2 + 13^2 = c^2
205 = c^2
<span>√205 = c

Answer
(-2,8)
Step-by-step explanation:
The first one is true
this is the equation: y=ax
you can put one of the points on the line as x and y. for example (2,8)
analyze problem
perfect circle with diameter of 20
so, radius is 10
circle circumference=10*pi*r
31.4*2
62.8
