Answer:

Step-by-step explanation:

A = x² - 5x - 14

Factor using AC method. Here, a = 1, b = -5, and c = -14.

ac = 1×-14 = -14

Factors of -14 that add up to -5 are -7 and 2.

A = (x - 7)(x + 2)

So the dimensions are x-7 and x+2.

What is the solution to this equation?<br> 7x + 3 = 10x - 5.4

stich3 [128]

Answer:

$x=2.8$

Step-by-step explanation:

$7x+3=10x-5.4$

Subtract 3 from both sides:

$7x+3-3=10x-5.4-3$

$7x=10x-8.4$

Subtract 10x from both sides:

$7x-10x=10x-8.4-10x$

$-3x=-8.4$

Divide both sides by -3:

$\frac{-3x}{-3}=\frac{-8.4}{-3}$

$x=2.8$
