$x^2 - 36=(x-6)(x+6)\\\\\\a^2-b^2 = (a-b)(a+b)$

No. It's the difference of two squares, and so can be easily factored:

x² - 36 = (x + 6) (x - 6)

Multiply those out and you'll see.

A bakery made 26 cherry pies, using 115 cherries for each pie. They threw away 36 cherries that were bad. If they used all the c

Artemon [7]

The bakery start with 2954 cherry

<em><u>Solution:</u></em>

Given that,

A bakery made 26 cherry pies, using 115 cherries for each pie

So they used 115 cherry for each pie

26 cherry pies, 115 cherry per pie

Therefore,

Number of cherries used = 26 x 115 = 2990 cherries used

They threw away 36 cherries that were bad

36 cherry were bad

2990 - 36 = 2954

Thus they start with 2954 cherries

A line passes through the point (2 comma negative 2 comma 10 ), and is parallel to the vector 9 Bold i plus 7 Bold j plus 10 Bo

lyudmila [28]

Title:

<h2>The standard parametric equation for the line is $\frac{x - 2}{9} = \frac{y + 2}{7} = \frac{z - 10}{10}$ .</h2>

Step-by-step explanation:

The standard parametric equation for a line generally represented as $\frac{x - a}{l} = \frac{y - b}{m} = \frac{z - c}{n}$ ; where (a, b, c) is the point that the line passes through and (l, m, n) is the direction vector of the line.

It is given that the line passes through the point (2, -2, 10).

Hence, here (a, b, c) ≡ (2, -2, 10).

Similarly, the direction vector of the line is given by (l, m, n) ≡ (9, 7, 10).

Putting all the values in the equation of the line, the equation becomes

$\frac{x - 2}{9} = \frac{y + 2}{7} = \frac{z - 10}{10}$ .

What is the answer 2p-a=3p+b if p is the subject of the formula

djverab [1.8K]

<em>*To solve for a variable, you have to isolate the desired variable onto 1 side</em>

So firstly, subtract 2p on both sides of the equation: $-a=p+b$

Next, subtract b on both sides of the equation, and <u>your answer will be $-a-b=p$ </u>

How do you solve this algebreically?<br> 3/8=x/20

Llana [10]

Answer:

7.5

Step-by-step explanation:

3/8 = x/20

3(20) = 8x

8x = 60

x = 60/8

x = 7.5
