-x-8+14x=-34 solve for x
Maksim231197 [3]

Answer:

X = -2

Step-by-step explanation:

-x - 8 + 14x = -34                                          

-x + 14x = -34 + 8

-x + 14x = -26

13x = -26

x = -26/13

x = -2


-(-2) - 8 + 14(-2) = -34

2 - 8 - 28 = -34

-34 = -34

Write as an expression and simplify:<br> The square of the difference of x and 8y
lukranit [14]

Answer:

x² - 16xy + 64y²

Step-by-step explanation:

The difference of x and 8y is x - 8y

The square of the difference is (x - 8y)² = (x - 8y)(x - 8y)

Expand by multiplying each term in the second factor by each term in the first factor, that is

x(x - 8y) - 8y(x - 8y) ← distribute both parenthesis

= x² - 8xy - 8xy + 64y² ← collect like terms

= x² - 16xy + 64y²
