Answer:
C) To square a number, multiply the number by itself.
Step-by-step explanation:
A) is incorrect because square roots are made by multiplying the number to itself.
2 × 2 is the same as 2²
3 × 3 is the same as 3²
4 × 4 is the same as 4²
2² = 4
3² = 9
4² = 16
B) is incorrect because the inverse of squaring is finding the square root.
2² inverse is √4
3² inverse is √9
4² inverse is √16
D) is incorrect because perfect squares can be odd or even
A perfect square is a number made by squaring a whole number.
4, 9, 16, 25, 36, 49, 64, 81, 100, 121, and 144 are all examples of perfect squares.
Answer is 181 sandwiches
Working steps
Firstly you want to work backwards and turn in equation
30*2+26*4+17=X
So 60+104+17=X
That means 181=X

Answer:
18.28 m
Step-by-step explanation:
Given the flower garden in the question :
The shape is composite and can be divided into 2 semicirles and rectangle
The perimeter of a semicircle is the Circumference of the semicircle = πr
Hence, 2 semicirles = 2πr
Radius of semicircle = 2/2 = 1
Perimeter = 2 * 3.14 * 1² = 2 * 3.14 * 1 = 6.28 m
The perimeter of rectangle; length and width are 6m and 2 m respectively :
Perimeter of rectangle = 2(l + w) = 2(4+2) = 2(6) = 12m
Tve perimeter of garden = 6.28 + 12 = 18.28 m
