Answer: 1st one
Step-by-step explanation:
5(3x-2)
Multiply everything in the parenthesis
15x - 10
It's the bottom one. Miko found the incorrect and checked her work using multipication incorrectly.
This is because the correct way to solve this would to use (5/1) * (3/5) = (15/5) then simplify it to 3/1 or simply 3.
Dividing fractions is simply flipping the second fraction and then multiplying across
A = 5 / 2 a^2 square root over 5 + 2 square root of 5
hopefully this helps you out
