Mono (1) nomial == 1 term.
11x^2 is 1 term in combination so B is your answer.
D. is not, its a binomial along with C. and A.
In order to find height (h), tan20 = h/26

Now for the left part of base (b1), where b2 = 26 and entire base (b) = b1+b2

So b = 13.03+26 = 39.03
Now Area (A) = 1/2bh = 1/2 (39.03)(9.46)
A = 184.59
The brackets make the answer positive so you were just do 48÷6 which is 8and then 35÷7 which is five and you add 8+5 and you get 13
Look at the 119. Would you say this is closer to 200 or 100? The answer is 22100. You just have to isolate what you are really looking at.
