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
