-5x + 5y = 40 -20x +20y =160 -5x + 5(8) = 40
4x + 3y = 24 20x +15y =120 -5x + 40 = 40
35y = 280 -5x =0
y = 8 x = 0
Hope you understood this
Answer: 38 in.^{2}
Step-by-step explanation:
1/ Find the area of the triangular sides. (1/2 x 2 x 6 =
for each triangular side)
2/ Find the area of each of the rectangular sides. In this case, the bottom (base) side is 2x6 =
. The rectangular side on the left is 2x3 =
, and the rectangular side on the right is 4x2 =
.
3/ Add everything together. Rectangular Sides + Triangular Sides = Surface Area ---> 
4/ You have your answer, now hope it helps ! :)
Answer:
61
Step-by-step explanation:
84+38=122
180-122=58
DBC=58
180-58=122
122÷2=61
61+58=119
180-119=61
17÷25=0.68
So it terminates.
Answer:
