Answer:
The first one and the second one.
Step-by-step explanation:
<span>No, because the mean is larger in the social studies book</span>
We write the translation one by one:
D (3, 5)
D' (-6, 2)
That translates to: (x - 9, y - 3), because that is for passing from D to D': (3 - 9, 5 - 3) = (-6, 2).
Therefore if it is true for D and D' then, it has to be true for all others (you can check) for that rule to be true, so the correct answer is:
(x, y)→(x − 9, y − 3)
Answer:
The new dimensions are 6 ft and 4 ft.
Step-by-step explanation:
Let x = side of original square.
The sides are increased by 3 ft and 1 ft, so the new side lengths of the rectangle are
x + 3 and x + 1
The area of the rectangle is length × width.
area = (x + 3)(x + 1)
area = x² + 4x + 3
The area is 24 ft².
x² + 4x + 3 = 24
x² + 4x - 21 = 0
(x + 7)(x - 3) = 0
x + 7 = 0 or x - 3 = 0
x = -7 or x = 3
x + 3 = 3 + 3 = 6
x + 1 = 3 + 1 = 4
The new dimensions are 6 ft and 4 ft.
