Answer: Heyaa! :D

Your Answer Is... 9

Step-by-step explanation:

Since both terms are perfect squares, factor using the difference of squares formula,

a²−b²=(a + b)(a − b) where a = B and

b = 9.

(B + 9)(B − 9)

Solve for x: -15x – 3 > 42

velikii [3]

Answer: X < -3

Step-by-step explanation:

-15x - 3 > 42

-15x - 3 + 3 > 42 + 3

-15x > 45

-15x/-15 > 45/-15

Since we are dividing by a negative, we flip the >

x < -3

So, let's check

-4 < -3

-15*-4 - 3 > 42

60 - 3 > 42

57 > 42

Now, let's see if -3 will work.

-15*-3 - 3 > 42

45 - 3 > 42

42 > 42 (False)

Okay, now let's try 4

-15*4 - 3 > 42

-60 - 3 > 42

-63 > 42

This is false, so it is x < -3

5r^2-13r-6=0 How do I solve this

frosja888 [35]

$5 {r}^{2} - 13r - 6 = 0 \\ a = 5 \\ b = - 13 \\ c = - 16 \\$

r= -(-13)±>

$\sqrt{( - 13) {}^{2} } - 4.5( - 6)$

2.5

r= 13±17

10

r=13+17

10

r=13-17

10

$r = 2 \\ r = \frac{ - 2}{5}$
