please hurry .The side of Mr. Miller’s barn has a length of 27 feet and an area of 656.1 square feet. How wide is the side of Mr
Art [367]

Answer:

24.3

Step-by-step explanation:

area of a rectangle =length*width

if we know at least the 2 quantities already

total area = 656.1

and one of the sides = 27

we have to divide the are by one of the sides to get the remaining side

width = area/length

656.1 divided by 27 equals 24.3

For f(x)=3x+1 and g(x)=x squared - 6 find (f- g)(x)
saveliy_v [14]
It helps to first clarify that the notation (f - g)(x) simply means f(x) - g(x). Given that, let's look at our f(x) and our g(x) here, and use their definitions to find their difference.

f(x)=3x+1\\g(x)=x^2-6

When we're taking (f - g)(x), we simply substitute the expression 3x + 1 for f(x) and the expression x² - 6 for g(x) to obtain:

(3x+1)-(x^2-6)=3x+1-x^2+6

Or, ordering the polynomial from highest power to lowest and combining the constants:

-x^2+3x+7

Edit: By request, here's what would happen if you had something instead like:

(f\times g)(x)

In this case, you'd have to *multiply* the two function expressions together. Here's what that would look like:

(3x+1)(x^2-6)

Using the distributive property, we can distribute the expression 3x+1 to the terms x^{2} and -6:

(3x+1)x^2-(3x+1)6

Distributing again, we get:

3x(x^2)+x^2-3x(6)+6=3x^3+x^2-18x+6

And we're done.

7r²+9=1 quadratic equation.
dezoksy [38]
<span>7r²+9=1 

</span><span>the equation is contradictory, just to prove

7r</span>² + 9 = 1

7r² + 9 -1 = 0

7r² + 8 = 0

<span>We write the equation in the form of products of
</span>
7 * (r² + 8/7) = 0

<span>the product is equal to 0 when one of the factors is zero
</span>
7≠0      ∨      (r² + 8/7) = 0
                     r² ≠ - 8/7
<span>any number squared is not negative.

</span><span>We proved that none of the factors is not equal to zero , so the right side of the equation is not equal to the left . The equation is contradictory</span>
