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
xenn [34]

Answer:

The product of (a+b)(a-b)  is a^2 - b^2

Step-by-step explanation:

Use FOIL to explain how to find the product of (a + b)(a − b)

FOIL is

Multiply First terms : a*a = a^2

Multiply Outside terms : a* -b = -ab

Multiply Inner  terms : b * a= ab

Multiply last terms : b * -b = -b^2

now we combine all the terms

a^2 -ab+ab - b^2

combine like terms

a^2 - b^2

The product of (a+b)(a-b)  is a^2 - b^2

Shortcut is we apply an identity

a^2 - b^2 = (a+b)(a-b)

A=5x+20 B=9x-92 Solve for x and then find the measure of A
Leviafan [203]
Because of the transversal and the parallel lines, we know that A+B=180°.

So:
5x + 20 + 9x - 92 = 180
14x - 72 = 180
14x = 180 + 72
14x = 252
x = 252/14
x = 18

A = 5x + 20
A = 5*18 + 20
A = 90 + 20 = 110

(Let’s check:
B = 9*18 - 92
B = 162 - 92
B = 70
70 + 110 = 180)
