During the 9 mile hike he spends 2 periods of half hour swimming = 1 hour.
actual hiking time = 3*3 = 9 hours

So total time = 9+1 = 10 hours

Find the solution.<br> -1.2x + 11.45 = 8.21<br><br> x = -2.7<br> x = 2.7<br> x = -4.6<br> x = 16.4

ddd [48]

Answer:

x = 2.7

Step-by-step explanation:

-1.2x + 11.45 = 8.21

Subtract 11.45 from both sides to get -1.2x = -3.24.

Divide both sides by -1.2 to get x = 2.7.

What is the factorization of the trinomial below -x^2+x+42

aksik [14]

For the given trinomial

$a=-1, b=1 ,c=42$

We need to multiply a by c
$-1 \times 42 = - 42$

We split the middle term with these two factors
$7,-6$
To obtain,

$- {x}^{2} + 7x -6x + 42$
We now factor

$- {x}^{2} + x + 42 \: = x( - x + 7) + 6( - x + 7)$
This implies

$- {x}^{2} + x + 42: = (x + 6)(7 - x)$
