Corresponding sides have the same ratio, so
x/15 = 12/(12+8) = 3/5
x = 15*3/5
x = 9
The answer to this question is
Both Parabolas open to the right, and x= 3y2 is wider than x= 5y2.

Answer:
(x ≤ -3) ∪ (11 ≤ x)
Step-by-step explanation:
The given equation resolves to two equations:
x -4 ≥ 7 ⇒ x ≥ 11
x -4 ≤ -7 ⇒ x ≤ -3
The solution is (x ≤ -3) ∪ (11 ≤ x).
Lateral area = surface area <em>not including</em> the bases.
To find this area we just need to add up the area of all of those sides.
The 2 bases are the same area and defined by the length and width.
That leaves the 2 sides defined by length and height,
plus the 2 defined by width and height.
Of course, to find the area of a rectangle, we just multiply together its two dimensions.
length × height = 14 × 6 = 84
width × height = 9 × 6 = 54
2 × 84 + 2 × 54 = 276 m²
