It would be difficult to help you.

It's all one big mess.
Was it supposed to be two or three separate expressions?
Answer:
37.3
Step-by-step explanation:
19tan(63) = x = 37.289... = 37.3
Answer: 1. 1/2 + try to figure out the rest I believe in you
Step-by-step explanation:
First cross simplify 1. 1/2 2/2 = 1/1 x 1/2, then multiply 1 x 1, then 1 x 2 = 1/2 for the first one, use the same for the rest.
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
The order goes 3, 2, 1, 5, 4 I think.
