Answer:
The interest is $20 per year
Step-by-step explanation:
6(G+9)
you have to use the distributive property.
6*G=6G
6*9=54
answer is 6G+54
The sum of the interior angles of a polygon is (n-2)*180, n being the number of sides.
a nonagon has nine sides, so the total of interior angles is (9-2)*180=7*180
this is a regular nonagon, so each interior angle has the same degrees:
7*180/9=7*20=140
the exterior angle=180-the interior angle=180-140=40
40 is the correct answer.
Answer:
50
Step-by-step explanation:
4,500÷90=50
and to check
90×50=4500
(for x=0) 3 & (for x=4) 19
