Answer:
A is quadrilateral
b is concave
c unsure but i belive it is regular correct me if I'm wrong
Answer:
44.7
Step-by-step explanation:
Speed = distance / time
speed from distance a to b = 50 = 10 / time
time = 10/50 = 12 minutes
Speed from a to c = 62 = distance / 30 minutes
distance = 62 x 0.5 = 31 m
diatance from b to c = 31 - 10 = 21
time = 30 - 12 = 28 minutes
speed = 21 / 28 minutes
31 / 0.47
Answer:
x = -2
Step-by-step explanation:
3(5x + 2) = 2(3x - 6)
<em>Expand the brackets. </em>
15x + 6 = 6x - 12
<em>Isolate the unknown variable x. </em>
15x - 6x = -12 - 6
<em>Evaluate. </em>
9x = -18
<em>Find x. </em>
x = -18 ÷ 9
x = -2
Answer:
108
Step-by-step explanation:
We can rewrite f(x+2) to make it easier to evaluate:
f(x+2) = (6x +5)x -8
Since we want f(6), we want x+2 = 6, or x=4.
f(6) = (6·4 +5)·4 -8 = 29·4 -8
f(6) = 108
