The original height of the plant is 20 inches, and each week for 4 weeks its height increases by 2h inches, so at the end of 4 weeks its height would be:
20 + 4(2h) = 20 + 8h
Now for the next two weeks the plant grows in height by h inches each week, so we need to add a further 2h inches to the equation. Thus the expression that shows the height of the plant after 6 weeks is:
20 + 8h + 2h = 20 + 10h, therefor A is the correct answer
1) 1/2 * 1/2 = 1/4
2) 43/100 of mine were heads, and (.43)^2 = .1849
3) 1/2 * 1/2 = 1/4
4)57/100 of mine were tails, and (.57)^2 = .3249
5) 1/2 * 1/2 * 2 (multiply by 2 because order doesn't matter) = 1/2
6) .43 *.57 = .2451
7) There is probably a difference becasue there wasn't enough data. The more times you flip the coin, the closer you'd get to 1/2 head 1/2 tails (theoretically), but you can't flip a coin an infinite amount of times, so it (usually) will not give you an exact 1:1 ratio between heads and tails
1/5. Divide both the numerator and the denominator by 20.
There’s probably a triangle or something above it that you’re supposed to reference, add a photo of it
