The left hand side of the equation is a difference of two squares and may be factored out as follows,
                              (x - 4)(x + 4) > 0
They may be individually taken as,
                                     x - 4 > 0    ; x > 4
                                     x + 4 > 0   ; x < -4
Thus, the answer to this item is letter A.

Can you simplify 8/15+1/6
belka [17]

Answer:

Yes and the answer is 16/5

Step-by-step explanation:

Find the reciprocal of the divisor

Reciprocal of 1/6 : 6/1

Now, multiply it with the dividend

8/15 ÷ 1/6 = 8/15 × 6/1

And after that you get 48/15 but after reducing the fraction, the answer is 16/5. ( In mixed form, 3 1/5 )

I hope this helps and I am a middle school student answering this question.

Situation One
navik [9.2K]

Step-by-step explanation:

Total no. of horses and chicken=24

C+H=24

Total no. horses be =24-C

Total no. legs=66

---66=4(24-C)+2C { As horses have 4 legs and chicken has 2 legs}

66=96-4c+2c

66-96=-2c

-30=-2C

Chicken=15

Therefore no. horses=24-C

=24-15

=9horses

There fore no. of chicken legs=15×2 = 30 legs

Therefore no. of horse legs=9×4=36 legs
