Answer:
the width is (x + 4) and the length is (x + 10)
Step-by-step explanation:
The area of a rectangle is given by A = L * W, where L is the length and W the width.
If we factor the given x^2 + 14x + 40, we get (x + 10)(x + 4). Thus, the width is (x + 4) and the length is (x + 10).
Answer:
X= -13
Step-by-step explanation:
X - 0.40x = 60
0.60x = 60
x = 60 / 0.60
x = 100 <== ur number
Answer:
(8, 5)
Step-by-step explanation:
Let's take a look at the y-intercept, (0, 5). If the axis of symmetry is x = 4, then the distance from (0, 5) is 4 units. If we reflect this point (0, 5) about the axis of symmetry x = 4, the resulting point is (8, 5). In other words, the distance from the y-intercept to the axis of symmetry is 4 units, and so the distance from the y-intercept must be 4 units plus 4 units, or 8 units.
The only answer choice that matches this is the second one: (8, 5).
