The answer is A. Radical sign 3.
The first term and common ratio for the geometric sequence are -3 and 5 respectively
<h3>Geometric sequence</h3>
This are sequence that increases exponentially. The nth term of the sequence is given as:
Tn = ar^n-1
where;
a is the first term
r is the common ratio
n is the number of terms
ar = -15
ar^3 = -375
Divide
r^2 = 375/15
r^2 = 25
r = 5
Determine the first term
a= -15/r
a = -15/5
a = -3
Hence the first term and common ratio for the geometric sequence are -3 and 5 respectively

Answer:
It's one of these. Depends if it's the answer or rewriting the equation. I beleive it's the first one tho
7+0.3+0.03 × 100+5
or
700+60+7+0.5+0.05
Answer:
14 sqr units
Step-by-step explanation:
divide the polygon into two triangle
the area of a triangle H = 1/2 *2 *7 = 7
so the area of the polygon = 2*H = 14
Listen, I'm not 100% sure on this one but i believe the answer is number 2.
Don't need to give me brainliest because i cant justify.
