Answer:

6(8 + 3x)

Step-by-step explanation:

There are an infinite number of equivalent expressions. We presume you have a list to choose from.

One of the more useful ones is the expression you get when you factor out the greatest common factor of the two terms. That factor is 6, so ...

48 + 18x = 6(8 + 3x)

Jerome bought screen for 59 cents per sq ft. how much did 12 sq ft cost

Gre4nikov [31]

Answer:

$7.08

Step-by-step explanation:

59 cents = 1 sq ft

? = 12 sq ft

To get from the 1 to the 12 we multiply by 12, so we must do the same to the 59 cents.

0.59 * 12 = 7.08

Therefore, the cost of 12 sq ft is $7.08.

Use FOIL to explain how to find the product of (a + b)(a − b). Then describe a shortcut that you could use to get this product w

andriy [413]

Greetings!

FOIL stands for:

Front
Outside
Inside
Last

This tells which terms to multiply when using the Distributive Property.
(NOTE: Only applicable with 2-term Polynomials)

For Example:
$(a+b)(a-b)$

Multiply the Fronts of both Equations:
$(a*a)$

Multiply the Outsides of both Equations:
$(a*a)+(a*-b)$

Multiply the Insides of both Equations:
$(a*a)+(a*-b)+(b*a)$

Multiply the Lasts of both Equations:
$(a*a)+(a*-b)+(b*a)+(b*-b)$

Simplify.
$=a^2-ab+ba-b^2$

$=a^2-b^2$

Alternative Method (My Prefered Method)
$(a+b)(a-b)=a(a+b)-b(a+b)$

Use Regular Distributive Property.
$a(a+b)-b(a+b)$

$a*a+a*b-b*a+-b*b$

Simplify.
$a^2+ab-ba+-b^2$

$a^2-b^2$

Hope this helps.
