Answer: x^2+29x+39

You would first have to set up an equation, which would be ((2x+9)⋅(x+6))-((x-5)⋅(x-3)) to find the area of both rectangles.

Then you can simplify it, which gives us 2x^2+21x+54-(x^2-8x+15)

Then simplify it even more which gives us 2x^2+21x+54-x^2+8x-15

Then we can get our answer: x^2+29x+39

Hope that helps :)

Which of the following best defines a function?

Sidana [21]

Answer: A. A function is a special type of relation for which there is a rule that pairs each input with exactly one output.

Option B is incorrect because it does not include that there cannot be two x-values with the same y-value. Option C is incorrect because it is a relation, not just a set of ordered pairs. Option D is incorrect because there is a particular pattern in a function.

Hope this helps!

Step-by-step explanation:

Given: Mrs Miller sells a house for 179,000.

She earns a commission of 6%.

we set up a proportions to find how much she earn.

Let x be the money does she earns then;

$\frac{179000}{100} =\frac{x}{6}$

Simplify:

$1790 = \frac{x}{6}$

Multiply both sides by 6 we get;

$1790 \times 6 = x$

Simplify:

x = 10,740

Therefore, she earns money is, 10,740

podryga [215]

Answer:

h = 16.92 m

Step-by-step explanation:

If you mean to man horizontal line of sight then the height of the tree is:

h = 2m + x

x is one right side and second is distance from the base of a tree 32m.

Tangence in this right triangle is:

tan 25° = x / 32 => x = 32 · tan 25° = 32 · 0.4663 = 14.92m

h = 2 + 14.92 = 16.92m
