Answer:18
Step-by-step explanation:
Note: Mathematicians start counting at 1, so by convention, n=1 is the first term. So we must define what the first term is. Then we have to figure out and include the common difference.
Taking a look at the examples again,
Sequence: 1, 2, 3, 4, … | Formula: a(n) = n + 1 | Recursive formula: a(n) = a(n-1) + 1, a(1) = 1
Sequence: 3, 8, 13, 18, … |Formula: b(n) = 5n - 2 | Recursive formula: b(n) = b(n-1) + 5, b(1) = 3
x = 17°
Step-by-step explanation:
total angle is 90°
so the equation is
90°=73°+ x
x = 90°-73°
x=17°
hope it helps ❤️
Answer:
FG=13
Step-by-step explanation:
We can make an equation that looks like this:
EF+FG=EG
Then, we can substitute in the numbers we know:
12+FG=25
Then solve:
FG=25-12
FG=13
Hope I helped soz if I'm wrong ouo.

64 is the answer, as all you need to figure out is the length, and width, and multiply them together. Or, just count each unit inside the shape.
