Answer:1125
Step-by-step explanation:
w=width
w+20=length
P=2l+2w
140=2(w+20)+2w
140=2w+40+2w
140=4w+40
140-40=4w
100=4w
w=100/4
w=25 m
l=25+20=45 m
A=lw
A=45*25
A=1125 sq m
Answer: The Jolene's unit rate in dollars per pound of grain is 0.25.
Explanation:
It is given that the Jolene is making a line graph that represents the price of grain and the number of pound purchase.
The number of pounds are shown on x-axis and the price in dollar are shown on y-axis.
The cost of 1 pound is 0.25, therefore the point (1,0.25) lies on the line.
The cost of 4 pound is 1, therefore the point (4,1) lies on the line.
The unit rate in dollars per pound of grain is the the slope of the line.
The slope of a line is,
Therefore, Jolene's unit rate in dollars per pound of grain is 0.25.

Step-by-step explanation:
the leading exponent is x^8 as it is the largest of the three (trinomial) the coefficient of x^8 is 6 as it is the number attached to x^8
I belive the answer is 4 or maybe 6 I think 6 is correct
Answer:
Step-by-step explanation:
cos a cos b+sin a sin b=cos (a-b)
cos 160 cos 10+sin 160 sin 10=cos (160-10)
=cos 150
=cos (180-30)
=-cos 30
=-√3/2
