A: 8*9= 72 or 72 because it is the lowest multiple of 8 and 9
B: euclidean theorem (35,63) (35,28) (7,28) (7,0) gcf= 7 or 7 because 7 is the biggest number that goes into both numbers.
C: 7(5+9) or 35 is a factored into 7 and 5 and 63 is factored into 7 and 9 and 9 is factored into 3 and 3
The correct answer is A.
lets discard the other options:
For B:
B is always positive, but f(x) is not, so B graph is not the answers
For C:
C is always positive too, so it cannot be the desire graph.
For D:
D is always negative, but we know that x exponent 3 is positive for all positive numbers,
We have to calculate the length of a side ( x ) of the rectangle. We know the perimeter of the rectangle: P = 24 ft. Formula for the perimeter of the rectangle is: P = 2 L + 2 W. The width W = 4 ft. So: 24 = 2 * x + 2 * 4; 24 = 2 * x + 8; 2 * x = 24 - 8; 2 * x = 16; x = 16 : 2; x = 8. Answer: The length of side of a rectangle is 8 feet<span>.</span>
the answer is c: .... 72+8w
