Calculate the following values:

adelina 88 [10]

F(a)=a^2-5a+7

F(a+h)=(a+h)^2-5(a+h)+7
=a^2+2ah+h^2-5a-5h+7

F(a+h)-F(a)=(2ah+h^2)/h

Factor out h, we will have h(2a+h)/h, the answer is 2a+h

Consider this expression

Sloan [31]

Answer:

$\displaystyle \large{(x + 9)(x - 8)}$

The value of a is 9 and b is -8

Step-by-step explanation:

$\displaystyle \large{(x + a)(x + b) = {x}^{2} + (a + b)x + ab}$

We need to find two numbers that add up or subtract off to 1.

Then we also use the same two numbers that multiply and get -72.

Let's see:-

9 and -8 seem like correct values.

Because 9+(-8) is 9-8 = 1

And 9(-8) is -72.

Therefore:

$\displaystyle \large{ {x}^{2} + x - 72 = (x + 9)(x - 8)}$

The value of a is 9 and the value of b is -8 according to form of (x+a)(x+b)

Suppose that a rectangle has an area of 54 square meters. Express the perimeter P as a function of the length x of one of the si

Lapatulllka [165]

Answer:

$P(x) = 2\left(x+\dfrac{54}{x}\right)$

Step-by-step explanation:

The area of the rectangle can be written as:

$A = x*h$

here, x is one side length, and h is the other side length. This area is said to be equal to 54 square meters.

$54 = x*h$

The perimeter of a rectangle can be written as:

$P = 2x+2h$

To express perimeter only in terms of x (in other words making it a function P(x)). we need to replace h. And this can be done by using the equation of area that we derived earlier.

$54 = x*h$

$h=\dfrac{54}{x}$

now we can substitute this 'h' into our equation of the perimeter.

$P = 2x+2\left(\dfrac{54}{x}\right)$

$P = 2\left(x+\dfrac{54}{x}\right)$

and voila! we have expressed P in terms of x only.

this can be written as P as a function of x as:

$P(x) = 2\left(x+\dfrac{54}{x}\right)$
