Answer:
Length = x feet = 95 feet
Step-by-step explanation:
The labeled triangles are not included in the question, therefore, I will calculate the length of the rectangular space for Kelly's dog
Perimeter of a rectangle = 2(length + width)
Perimeter of a rectangle = 236 feet
Width = 23 feet
Length = x feet
Perimeter of a rectangle = 2(length + width)
236 = 2(x + 23)
236 = 2x + 46
236 - 46 = 2x
190 = 2x
x = 190/2
x = 95 feet
Length = x feet = 95 feet
Answer:
A. 2 factors: 5 and (6+4x)
B. 5: 1 term
(6+4x): 2 terms
C: The coefficient is 4
Step-by-step explanation:
The factors are the parts of expression separate by multiplications, so there are 2 factors: 5 and (6+4x)
The terms of each factor are the terms separate by the sign + or -. So the term of the factor 5 is 1 and the terms of the factor (6+4x) are 6 and 4x
The coefficient of the variable term is the number that is beside the variable. The coefficient of x is 4.
