Answer:
9, 30, 27
Step-by-step explanation:
To find the perimeter, you must add up each side. In this scenario, we know that the perimeter is 66 feet. We also know the sides, which are n, 3n+3 and 4n-9.
So, we must add the sides to get 66 feet.
n+3n+3+4n-9=66
Combine like terms, and solve:
(n+3n+4n)+(3+-9)=66
8n+-6=66
8n-6=66
n=9
So if n=9, we can easily find the value of the other sides.
3(9)+3=30 feet.
4(9)-9=27 feet
So, the sides are 9, 30, and 27 feet (in order).
Answer:M=4
Step by step answer
9x^2-mx^2+12x-3=5x^2+12x-35
9x^2-mx^2+12x-3+3=5x^2+12x-35+3
9x^2-mx^2+12x=5x^2+12x-32
9x^2-mx^2+12x-12x=5x^2+12x-32-12x
9x^2-mx^2-5x^2=5x^2-32-5x^2
-mx^2+4x^2=-32
x^2(-m+4)=-32
M=4
Hope this helps (;
1.05+0.125+.075 = 1 1/4
(B) I Really dont know what it means for the second one
I think the correct answer would be both the mean and median are appropriate measures of center. Since the given data set is ordinal and is not skewed that much. Also the values of such would be close with each other. Hope this answers the question.
