Here is your answer: Combine like terms: 4a+2a=6a and 8b-6b=2b Your answer is 6a+2b
1. H and E i dont know the rest if I’m being completely honest but there’s the first one for you
Step-by-step explanation:
multiple possibilities.
e.g.
we could use Pythagoras to get QR, and then use the law of sine to get angle P.
or we can use the law of sine to get angle R, and then use the rule that the sum of all angles in a triangle is always 180° to get angle P.
I propose the second option :
the law of sine :
a/sin(A) = b/sin(B) = c/sin(C)
with a, b, c being the sides always opposite of their associated angles.
33.8/sin(R) = 57.6/sin(90) = 57.6
sin(R) = 33.8/57.6 = 0.586805555...
R = 35.93064691...°
180 = 90 + 35.93064691... + P
P = 54.06935309...°
10.79/1200=.009
.009*1200=10.79 this is a double check to make sure our price per square foot is correct.
.009*4000=$36.00
It will cost $36.00 to seed the 4,000 square feet at that price.
