Answer:
380≠−17
Step-by-step explanation:
3(182+2)−172
?=
−17
380≠−17
Answer:
see explanation
Step-by-step explanation:
Given the recursive formula
=
and
= 2
=
, then
=
( multiply both sides by 4 )
a₃ = 4 ×
= 9
= 9 ( multiply both sides by 4 )
a₂ = 36
= 36 ( multiply both sides by 4 )
a₁ = 144
The first 4 terms are
144, 36, 9, 2 
The diameter is 9.
Circumference=pi*diameter
9 pi/pi=9
Hope this helped☺☺
Check whether it is possible to have a triangle with the given side lengths for example 7,9,13 then add any two sides and see if it is greater than the other side. Example the sum of 7 and 9 is 16 and 16 is greater than 13
Answer:
x=36
Step-by-step explanation:
The 2 angles, ∠EAF and ∠FAB are on a straight line. This means they are supplementary, and add to 180 degrees.
So,
∠EAF +∠FAB =180
We know that ∠EAF is 3x and ∠FAB is 2x, so we can substitute them in
3x+2x=180
Combine like terms
5x=180
Divide by 5 on both sides
x=36
So, x=36 degrees, or the last choice
