You didn't give any answers, but, I hope this will help you out a bit:
for example, if the air freshener sprays 3 times every 20 minutes,
here are our points:
(20,3), (40,6), (60,9), (80,12)
lets take the second and third point to find the slope.
3/40 would be the slope.
graphing slope
the slope would be 3/5
The required simplified solution of the given expression is -4.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
= -6 - |3 - 7| × 4 ÷ 8 - (-2)
Simplifying the above expression using the PEMDAS rule,
= -6 -|-4|×4÷8+ 4
= -6 - 16÷18 + 4 [∵ |-4| = 4]
= -6 - 2 + 4
= -4
Thus, the required simplified solution of the given expression is -4.

b. Write an equation in standard form representing the area of the picture and the frame. Explain how you arrive at your osition.
Answer: a) Quadratic equation b)
Step-by-step explanation:
Since we have given that
Length of photograph = 8 inches
Width of photograph = 10 inches
It is surrounded by a frame with uniform width 'x'.
So, Length of picture and frame becomes
Width of picture and frame becomes
So, Area of picture and frame becomes
Hence, a) Quadratic equation b)
Answer:
l=95
Step-by-step explanation:
Perimeter is all the sides add up. So the equation if you know two of the sides, it should be: 338=(2*74)+(2*l)
Answer:
Step-by-step explanation:
the perimeter is 2w plus 2l
so 338 = 74(2)+2l
338 = 148+2l
190=2l
l=95
your length would be 95 m
