Area of the 2 right triangles =2 (1/2 x 1.5 x 2 ) = 3 in²
Area of the 3 rectangles = (1.5 + 2 + 2.5) x 11 = 66 in²
Total Surface area = 3 + 66 = 69 in²
Answer: 69 in²
4/15 = 0.267
8/25 = 0.32
0.267/0.32 = 0.834375
Answer:
Shane started the problem correctly
Step-by-step explanation:
We are given problem (-5) - (-1 3/4).
Mariah started the problem as (-5) + 1 - 3/4
Shane started the problem as (-5) + 1 + 3/4
We need to find who started the problem correctly.
The problem should be started by converting the mixed fraction into improper fraction i,e

Now we will solve bracket by multiplying -1 with term inside the bracket i.e


Let's compare both the procedures now:
Mariah:



Therefore, Mariah did not start the problem correctly.
Shane:



Therefore, Shane started the problem correctly.
2 lines intersect at one point and stop there to form an L shaped angle they also form a square when you combine another right angle and they measure 90 degrees. Hope this helps!
x={1+i√19 , 1-i√19}
solve this by using quadratic formula
