Answer:
x = 20
Step-by-step explanation:
50 - 38 = 12
a^2 + b^2 = c^2
16^2 + 12^2 = x^2
256 + 144 = x^2
400 = x^2
x =
x = 20
Answer:
Step-by-step explanation:
<u>Geometric Sequences</u>
The geometric sequence is given as:
Where n is the number of the term, n≥1, and r is the common ratio.
The sum of n terms of the geometric sequence is given by:
We are given: S3=252, a1=192, thus substuting:
Dividing by 12:
Recall that:
Substituting:
Simplifying:
Rearranging:
16r^2+16r-5=0
Rewriting:
Factoring:
Solving:
Both solutions are valid
Answer:
144
Step-by-step explanation:
x^2+24x=17
b=24
(b/2)^2=(24/2)^2=12^2=144
