35% was damaged.
1 percent is 400 acres, so 14000/400= 35% of forest was burned
The answer will be x squared over 4 plus y squared over 8 equals 1.
<h3> What is an ellipse?</h3>
An ellipse is an oval shape geometry having two focuses and the curve is equidistant from the focus.
The general equation of the ellipse is given as;
(x²/a²) + (y²/b²) = 1
The coordinates of a foci are: (±c, 0) where;
c² = b² - a²
However, we know that equation of directrix is; x = ±a/e
Now, Directrix is given ±4
Thus, a/e = 4
a = 4e
We also know that c = ae from ellipse foci coordinates.
Thus, ae = 2
since ae = 2, then (4e)e = 2
4e² = 2
e² = 2/4
e = 1/2
Thus;
a = 4 × 1/2
a = 2
Since c² = b² - a²;
2² = b² - 2²
4 = b² - 4
b² = 8
From (x²/a²) + (y²/b²) = 1, we can put our values to get;
x²/4 + y²/8 = 1
Hence the answer will be x squared over 4 plus y squared over 8 equals 1.

The equivalent expression is 30x + 15y
<em><u>Solution:</u></em>
Given that we have to find the equivalent expression for given expression
<em><u>Given expression is:</u></em>
5(6x + 3y)
We can find the equivalent expression by using distributive property
The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.
<em><u>By distributive property,</u></em>
a(b + c) = ab + ac
Therefore, in given expression 5(6x + 3y), 5 can be multiplied with both 6x and 3y
Multiply the numbers and simplify
Thus the equivalent expression is 30x + 15y
Answer:
