5 Experimental Scenarios
Jackle read that Aloe Vera promoted healing burned tissue. She decided to investigate the effect of varying
amounts of Aloe on the regeneration of planaria - a small organism. She bisected the planarla to obtain 10 parts (5
heads and 5 tails) for each experimental group. She applied concentrations of 0%, 10%, 20%, and 30% Aloe to the
groups. 15 mL of Aloe solutions were applied. All planarla were maintained in a growth chamber with identical
food, temperature, and humidity. On Day 15, Jackle observed the regeneration of the planarla parts and
categorized development as full, partial or none.
What is the constant?

8+2x and 3(x+4)-(4+x)

Step-by-step explanation:

2(x+4)=2x+8 interchanged to 8+2x

3(x+4)-(4+x) simplified to

3x+12-4-x collect like terms together 3x-x+12-4=2x+8
