What is the following product ?

AfilCa [17]

Answer:

The correct answer is option B). 7x² -12x√14 + 72

Step-by-step explanation:

Identity

(a - b)² = a² - 2ab + b²

Find the product

It is given that ( x√7 - 3√8)(x√7 - 3√8)

(x√7 - 3√8)(x√7 - 3√8) = (x√7 - 3√8)²

(x√7 - 3√8)² = (x√7)² - 2*x√7*3√8 +(3√8)²

= 7x² - 6x√56 + 72

= 7x² - 6x*2√14 + 72

= 7x² - 12x√14 + 72

Therefore the correct answer is option B). 7x² - 12x√14 + 72

What is the product? −5⋅(−3)⋅(−8) A.-120 B.-16 C.16 D.120

Paha777 [63]

The product of the given expression is -120. Option A is correct

<h3>Product of negative numbers.</h3>

Given the expression below as shown;

−5⋅(−3)⋅(−8)

Since the product of two negative number is equal to positive, then;

−5⋅(−3)⋅(−8) = -8(5*3)

Simplify the result to have:

-8 * 15

find the final product

-8 * 15 = -8(5+10)

-8 * 15 = -40 - 80

-8 * 15 = -120

Hence the product of the given expression is -120

Six times a number increased by 20 is four less than eight times the number. Find the number

DaniilM [7]

Greetings!

"Six times a number increased by 20 is four less than eight times the number. Find the number."...

This would be, as an equation:
 $6x+20=8x-4$

Solve:
Add 4 and -6x to both sides.
$(6x+20)+4+(-6x)=(8x-4)+4+(-6x)$
Simplify.
$24=2x$
Divide both sides by 2.
$(24)/2=(2x)/2$
Simplify.
$12=x$
$x=12$

x=12

Hope this helps.
