Answer:
Step-by-step explanation:
The common ratio of a geometric sequence can be found dividing the current term in the sequence by the previous term in the sequence. In other words, where:
is the common ratio of the geometric sequence
is the current term in the sequence
is the previous term in the sequence
- For and
- For and
Since the ratio is the same for both pair of number in the geometric sequence, we can conclude that 5 is the common ratio of the sequence.

Answer:
Step-by-step explanation:
= x²(-3 +5) +y²(2 -3) +5xy -2y
= 2x² -y² +5xy -2y
a) there are 4 terms in the simplified expression
b) 2 terms have negative coefficients (-y² and -2y)
The answer is
the first one is x= 18.98
a^2+b^2=c^2
8 cm^2+17 cm^2= x^2
64+289=x^2
√x^2= √353
x=18.89
<span><span>the second one is x= 18.7
a^2+b^2=c^2
7 m^2+ x^2= 20 m^2
49 m+x^2=400 m
-49 -49
</span></span>√x^2=√352
<span><span>x= 18.7
Hope this helps!</span></span>
