Answer:
The area is the side lengths squared or multiplied by themselves. The three squares have very different areas based on their side lengths. I disagree that a square with 13 inch side length will have area 13. It will have area 13*13=169 square inches.
Step-by-step explanation:
The area of a square is A=s*s.
1st: A = 1*1 = 1 square inches.
2nd: A=1/2*1/2 = 1/4 square inches
3rd: A =2*2 = 4 square inches.
The area of a square with 1 unit side length is still 1. But a square whose side is less than 1 has a very small area and the square whose side length is greater than 1 has a much larger area. The area of a square is the square of its side length or its side length times itself.
Knowing this, a square with side length 13 will not have area 13 but area 169.
Answer:
x = -4 ; y = 1
Step-by-step explanation:
2x + 6y = -2 --------(i)
-x + 2y = 6 --------(ii)
2x + 6y = -2
(ii)*2 <u> -2x + 4y = 12</u>
add; 10y = 10
y = 10/10
y = 1
Substitute y in (i)
2x + 6*1 = -2
2x +6= -2
2x = -2-6
2x = -8
x = -8/2
x = -4
Answer:
The cube root of a number is a special value that, when used in a multiplication three times, gives that number. Example: 3 × 3 × 3 = 27, so the cube root of 27 is 3. See: Square Root. Cubes and Cube Roots.
Answer:
4.5^3 because we know v=lwh. since its a cube l, w, h will all equal 4.5
123.4651163 or rounded to 123.47
