Answer: Is your question "What is the length of each side?"
Let x = the length of the second side
Let x - 5 = the length of the first side
Let (x - 5) - 2 = the length of the third side
P = a + b + c
x + x - 5 + x - 7 = 42
3x - 12 = 42
3x = 54
x = 18 yards
x - 5 = 13 yards
x - 7 = 11 yards

Answer:
Q1 A Scatter plot. Q2
Step-by-step explanation:
Q1. We have a data set containing values of car and age group, if we plot value of the car on y-axis and the age on x, it is logical that two different age groups can own a care with same value, so we can have two values on x corresponding to one value on the y-axis, if we can use scatter plot to visually depict this data.
Q2 50 couples with bride age and groom age , here we can take age difference and number of couples that fit in the catogery, a two way table can be used to describe this data(two columns ).
Answer:
Step-by-step explanation:
<u>Assume a solution</u>
Assume that 60 is the length. The width is then 1/4 less, or 60 -60/4 = 45.
The diagonal of this rectangle is found using the Pythagorean theorem:
d = √(60² +45²) = √5625 = 75
<u>Make the adjustment</u>
This is a factor of 75/40 larger than the actual diagonal, so the actual dimensions must be 40/75 = 8/15 times those we assumed.
length = (8/15)×60 = 32
width = (8/15)×45 = 24
The length and width of the rectangle are 32 and 24, respectively.

<em>Comment on this solution method</em>
This method is suitable for problems where variables are linearly related. If we were concerned with the area, for example, instead of the diagonal, we would have to adjust the linear dimensions by the <em>square root</em> of the ratio of desired area to "false" area.
