Answer:
D) 394.68cm^2
Step-by-step explanation:
Area of a parallelogram is calculated by multiplying height to the base
13.8 × 28.6 = 394.68
Okay so you know a straight line is equal to 180 degrees, so you set them up in an algebraic equation. (5x+2)+48=180 subtract 48 first to get 5x+2=132 Subtract the 2 this time to get 130. Now you end up with 5x=130. Here you divide 130 by 5 to get X=26. If you just need to find the degree of that angle tho you can stop after the first subtraction because the math tells you (5x+2)=132 degrees.
Answer:
basicly you divided muiltiply and subtract bring back down then bring it on back
The answer is 1,342 cm squared. This problem is fairly simple, but ok.
Brand A has a unit price of .37 cents
brand B has a unit price of .38 cents
so you get 2 more pencils for .1 cent each, so brand B is the better deal
