Answer:
60
Step-by-step explanation:
shape can be made into a trapezoid and square
rectangle area= a*b
triangle = 1/2 a*b
rectangle = 64
triangle = 4
64-4=60
Just plug in 9 for n
a(n) = 7 - 9n
a(9) = 7 - 9(9)
a(9) = 7 - 81
a(9) = -74
so the 9th term is -74
The answer would be 1.6666666668

Answer:
ABC are the marked vertices (points) of a triangle. They join each line ie) A to B= AB A to C= AC B+C=BC. We can when working on combined lines and shapes call the exterior vertices away from the triangle D and E when making reference to finding measurements of adjoining shapes/lines, but not to ABC. We can also use AB to determine the midway point as a independent or alternative use.
We usually see A on the opposite point of a right angle.
