Factor 64 - P. (8 - x(8 - x) (8 + x (8 - x) (X + 8)(x-8)

Question:

Factor $64-x^2$

(8 - x)(8 - x)

(8 + x) (8 - x)

(X + 8)(x-8)

Answer:

Option B: $(8+x)(8-x)$ is the factor

Explanation:

Given that the expression is $64-x^2$

We need to find the factor of the given expression.

Let us rewrite the expression as $8^2-x^{2}$

Since the expression is of the form $a^2-b^2$ , let us use the identity $a^2-b^2=(a+b)(a-b)$

where a = 8 and b = x

Substituting the values in the identity, then the expression can be written as

$8^2-x^{2}=(8+x)(8-x)$

Thus, the factor of the expression is $(8+x)(8-x)$

Hence, Option B is the correct answer.

stiv31 [10]

All you have to do basically is make up an equation of your own and then plug in the numbers inplace of the variables while still keeping the equation true.

The answer can be anything from : 8-4= 2+2
And all you had to do was simply plug in numbers to make it true. Hoped i helped!

Your furniture store sells two types of dining room tables. The first, type A, costs $210 and you make a $21 profit on each one.

zimovet [89]

Answer

In order to minimize total cost sell A type 40 numbers and B type 90 numbers

Solution

furniture store sells two types of dining room tables.

The first, type A, costs $210 and you make a $21 profit on each one.

The second, type B, costs $180 and you make a $20 profit on each one.

We can order no more than 130 tables this month, and you need to make at least $2640 profit on them.

Let x be the number table Type A sold, type B sold = 130-x

To find the value of x

21x +(130-x)20=2640

solving we get x=40

There are two possibilities

A type sold =40 B type sold = 130 - 40 =90

total cost = 40 x 210 + 90 x 180 = 24600

A type sold =90 B type sold = 130 - 90 =40

total cost = (90 x 210) + (40x180)=26100

In order to minimize total cost, choose first possibility

sell A type 40 numbers and B type 90 numbers
