Answer:
The simplified expression of your question is
11n/2-p/2-2
Answer:
194 square units
Step-by-step explanation:
perimeter is the measurement of the distance surrounding a shape. There fore, the perimeter of the shape is: 42+53+56+44=194 square units
(-3,11) & (1,-3)
x1 y1 x2 y2
-3-11 -14 -7
1+3 4 2
y=-7/2x+b
11=-7/2(-3) +b
11=21/2+b
22/2=21/2+b (subtract 21/2 from each side)
1/2=b
so it would be y=-7/2x + 1/2
Sub in the numbers
3(8)(7) + 8(7) - 5(8)
=168 + 56 - 40
=224 - 40
=184
