Answer:
87
Explanation:
This is an arithmetic sequence with <u>common difference</u>: 7 and <u>first term</u>: 17
Arithmetic sequence:
a + (n - 1)d where n is term position, d is difference, a is first term
17 + (n - 1)7
7n + 10
The eleventh term:
7n + 10
7(11) + 10
77 + 10
87
Answer:
1. BC=25
2. DC=30
Step-by-step explanation:
In a parallelogram, pairs of opposite sides are always equal. The side opposite of AD is BC, so if AD=25, BC=25. Likewise, if side AB=30, side DC=30. Of course, this is assuming the shape is a parallelogram. If it is not, there is no way of determining the side lengths.
lmk if im wrong, hope this helps :)
