Answer:
45
Step-by-step explanation:
45 is constant, because no mater how many miles you drive, you will always be charged $45. It stays the same
We know that the area of a rectangle is length * width, and the area of a triangle is 1/2 * base * height. However, we know that the areas are equal, or that
lw = 1/2bh
If we substitute in the measurements that we know, we can solve the following equation for x.
5x + 1 (x) = 1/2(8x)(x+1)
Let's simplify this equation by multiplying.
5x² + x = 4x² + 4x
Now, let's bring all of the variables to one side of the equation.
x² - 3x = 0
Finally, we should factor out the Greatest Common Factor.
x(x-3) = 0
Therefore, by the Zero Product Property, x = 0, 3. But since the measurement of the short side length of the rectangle is x, it cannot be zero. Thus, x = 3.
The question asks for the area of the rectangle, which is <span>5x² + x.

Let's solve this expression for x = 3.
5(3)² + 3
5(9) + 3
45 + 3
48
Therefore, the area of the rectangle is 48 square units, or option B.
The normal price of each cookie is $1.15 derived from the equation, c =today price of each cookie + 0.75
<u>Solution:</u>
Given, Today each cookie costs 0.75 less than the normal price.
Right now if you buy 7 of them it will only cost you 2.80
We have to write an equation to determine the normal price of each cookie(c)
And, we are given that, today 7 cookies cost 2.80
Let the cost of one cookie today be “n”
Then we get,
Today 7 cookies ⇒ 2.8
Then, 1 cookie ⇒ n
By criss cross multiplication we get,
Which means that, each cookie costs $0.4 today
Now, we know that,
<em>normal price of each cookie, c = today price of each cookie + $ 0.75 </em>
c = 0.4 + 0.75
c= 1.15
Hence, the normal cost of each cookie is $1.15 derived from the equation, c = today price of each cookie + 0.75
