The answer would be y=-4 and x=4, so pick which ever number/letter has this answer.
This is unreadable try submitting a more clear picture. i can bairly read the first problem i think it says 8(3x+4)=2(17x????)
Answer:
3x + 2 = 3x - 2
Step-by-step explanation:
Answer:
Step-by-step explanation:
Use the exponential form of this log equation. Rewriting this into exponential form gives us
5-squared is 25, so
25 = 2x - 3 and
22 = 2x so
x = 11
The sum of all of the exterior angles of any regular polygon is 360 (I'm assuming by decagon you mean a regular dodecagon).
Because the total has to be 360, and a decagon has 10 sides, you divide 360 by 10 to get each exterior angle.
360 ÷ 10 = 36, so each exterior angle of a decagon is 36 degrees.
