<h3>What is geometrical series?</h3>
A geometric series is the collection of an unlimited number of terms with a fixed ratio between them.
Given the value of a₁=9 and the value of . Therefore, the value of a₅ can be written as,
a₂ = -3(a₁) = -3(9) = -27
a₃ = -3(a₂) = -3(-27) = 81
a₄ = -3(a₃) = -3(81) = -243
a₅ = -3(a₄) = -3(-243) = -729
Hence, the value of a₅ is -729.

Hey there! :D
So, you know the x value. Plug that value in.
-3(-5)+7y= 5(-5)+2y
15+7y= -25+2y
Subtract 15 on both sides.
7y= -35+2y
Subtract 2y on both sides.
5y=-35
Divide both sides by 5.
y=-7.
(-5,-7) <=== the solution.
I hope this helps!

(4x-13)°+15°+(x+18)°=180
4x-13+15+x+18=180
5x+20=180
5x=180-20
x=32
A=(4x-13)°
=(4×32-13)°
=115°
C=x+18°
=32+18°
=50°
HOPE IT HELPS UH!!☺️☺️
