The area of rectangle ABCD should be 24. Since the length is 6 and the height is 4.
Answer:
53/8 or 6.625
Step-by-step explanation:
10 + (-3 3/8)
Convert everything to a fraction having the same denominator.
<u>-3 3/8</u>
-24/3 - 3/8
-27/8
<u>10</u>
80/8
Combine: (80/8 - 27/8) = 53/8 or 6.625
A(n)=a(1)+d(n-1)
a(1)=8
a(4)= 8+d(4-1)
17=8+d*3
17-8=3d
9 =3d
d=3
a(n)= 8 +3(n-1) Sometimes it is required like this.
Sometimes , it is required to simplify more
a(n)=8+3n-3=5+3n
a(n)=5+3n
