L=w+2 and 2w+2l=44
substitute equation for length in perimeter equation
2w+2(w+2)=44
2w+2w+4=44
4w+4=44
4w=40
w=10
substitute width into length equation to get length
l=10+2
l=12
a=lw
a=12*10
a=120 cm^2
Answer:
67.5 degrees
Step-by-step explanation:
The angle between the 6 and the 9 = 90 degrees.
WE can say that the hour hand is ' 3/4 of 5 minutes' past the 6.
5 minutes is equivalent to 360 / 12 = 30 degrees.
Thus the angle between the 6 and the hour hand
= 30 * 3/4
= 22.5 degrees.
The required angle is 90 - 22.5
= 67.5 degrees.
(8, 9) will be the midpoint of the segment.
You can find this by applying the formula
(x1 + x2)/2 , (y1 + y2)/2
The answer is B! Because 5 x 5 x 5 x 5 = 625
