2) 1 4/5
3) 2
4) 4 1/3
5) 3 4/8 or 3 1/2
6) 6 2/8
Ok to start you need to break this into a net in your head. Next, calculate each triangle
(6*7)/2 = 21
Then, multiply each triangle by the amount of them.
21*4 = 84
Next, get the area of the square.
7*7 = 49
Lastly, add the triangles and the square up.
49 + 84 = 133
This can be easily figured out. Check to see what points are on the bottom and that is your answer.
B
A=LW
192=(13+x)((9+x)
192=117+22x+x^2 (subtract 192 from both sides)
x^2+22x-75+0 (factor)
(x+25)(x-3)=0
so x=-25 or 3
Check work
since we are adding x it can only be the positive solution so x=3 so the new dimensions are:
L=13+3=16m
W=9+3=12
check: 16*12=192 so the answer is correct hope this helped
Answer:
its supposed to be 120 degrees because the angle picture thingy looks like its an obtuse angle and too big to be 60 degrees
