Step-by-step explanation:
d^2+35+109=180
144+d^2=180
-144 -144
36=d^2
d=6

Answer: First option 13
Solution
If ABCD is a rhombus, the diagonals must be perpendicular, then the angle (5x+25)° must be a right angle (90°):
(5x+25)°=90°
5x+25=90
Solving for x: Subtracting 25 both sides of the equation:
5x+25-25=90-25
Subtracting:
5x=65
Dividing both sides of the equation by 5:
5x/5=65/5
Dividing:
x=13
Answer: The value of x must be 13
Answer:
The explicit form for the sequence is: 
Step-by-step explanation:
In order to find an explicit form for the given sequence, you have to use the definition of arithmetic sequence and the <em>explicit formula</em>.
An arithmetic sequence is defined as a sequence where the difference of two consecutive terms is a constant.
The <em>explicit formula </em>is:
Where a1 is the first term, d is the common difference and an is the nth term of the sequence.
You have to subtract two consecutive terms to obtain d:
24-13= 11
35-24=11
Therefore d=11
In this case a1=13
Replacing in the formula:
Answer:
an = 6n -2
Or
an+1 = an +6
Step-by-step explanation:
to go from 4 to 10 we add 6 tiles
to go from 10 to 16 we add 6 tiles
We add 6 tiles each time
an = a1 + d(n-1) where an is the value of the nth term a1 is the first term d is the common factor and n is the term number
an = 4 + 6( n-1)
an = 4 + 6n -6
an = 6n -2
Or
an+1 = an +6
