The Simplification of the expression 7 exponent 7/7 exponent 4 is 7³
<h3>Exponent</h3>
7 exponent 7/7 exponent 4
= 7^7 ÷ 7^4
Using the law of indices which states that:
- Division of an exponential expression with equal base should be subtracted
7^7 ÷ 7^4
= 7^(7-4)
= 7^3
Therefore, the Simplification of the expression 7 exponent 7/7 exponent 4 is 7³

Imagine a rectangular area that represents the garden. Then, add a uniform margin of 2 ft around it. So, the length and width dimensions of the bigger outer rectangle would be added with 4 ft each, accounting for two 2-ft marginal distances on both ends. This would be the perimeter:
2(L+4) +2(W+4) = 46
Since L = 2W
2(2W +4) + 2(W+4) = 46
4W + 8 +2W + 8 = 46
W = 5 ft
L = 2(5) = 10 ft
Therefore, the dimensions of the garden is 10 ft in length and 5 ft in width. The area, consequently, is calculated as:
A = LW
A = (10 ft)(5 ft)
A = 50 ft²
Thus, the area of the garden is 50 ft².

Step-by-step explanation:
Since the axis of symmetry is vertical and the vertex of the parabola is at (12,-4), the vertical line x=12 is the axis of symmertry. The x-distance between the axis of symmetry and the first x intercept (15,0) is equal to 15-12=3. Hence, this x-intercept is 3 units to the right of the axis, and because it is symmetric, the other x-intercept must be 3 units to the left of the axis, so its x-coordinate must be 12-3=9. Then, the other x-intercept is at the point (9,0)
