Answer: B.16
Step-by-step explanation:
(s - 2) × 180 = 2520
s- 2 = 14
s = 16
answer
B. 16
Answer:
all real numbers
Step-by-step explanation:
The domain are the values of the input values x that makes the given function exist
Given the function:
y= x^2+4x
Since x^2 is a perfect square, the value of x can exist on all real numbers
Hence the domain of the function is all real numbers
Answer:
x= -4 y=5
Step-by-step explanation:
Answer:
The remaining piece measures 16 m
which agrees with answer D
Step-by-step explanation:
In order to make a square of area 25 m^2, we need a square of side 5 m ,
Area of square = side^2
25 = side^2 then each side = 5 m
therefore the person needed 4 times 5 m to create the square, that is 20 m for the square. Therefore the piece that is left can be calculated with the difference:
36 m - 20 m = 16 m
The remaining piece measures 16 m
Answer:
11
Step-by-step explanation:
Put the values where the variables are and do the arithmetic.
m*n = √(m³ -n²)
5*2 = √(5³ -2²) = √(125 -4) = √121
5*2 = 11
