558.7 , because 74 x 7.55 = 588.7 , it would be his total for the two weeks
A = (1/2)(x)(y)
Let x = diagonal 1
Let y = diagonal 2
The product of xy = 144.
This means that x = 12 and y = 12.
So, 12 • 12 = 144
Each diagonal is 12 feet.
Prove:
72 feet = (1/2)(12)(12) feet
72 feet = (1/2)(144) feet
72 feet = 72 feet
Answer: |-10| < |11|
So choice C. is right.
hope this helps!
The answer is: x = 10, y = 2
Leave a thanks because your welcome :)
Work:
x + y = 12
(10) + (2)+ = 12
Correct
x - 2y = 6
(10) - 2(2) = 6
10 - 4 = 6
Correct
3/3 = 1
4/4 = 1
1 × 1 = 1
3/3 × 4/4 = 1
