Answer:
d
Step-by-step explanation:
there is only 4 of her ponies that are over 96 centimeters but it is not 40 percent but 27 percent because she has 14 ponies not 10 ponies
The answer is 10.8. You turn 10 4/5 into 54/5. Then you divide 54 by 5.
Answer:
The roots are +/- 5 and +/- 4i or 5, -5, 4i, -4i
Step-by-step explanation:
Begin by dividing through by - 3
-3x^4 / - 3 + 27x^2/-3 + 1200/-3 = 0
x^4 - 9x^2 - 400 = 0 This makes it easier to work with. Substitute
z = x^2
z^2 - 9z - 400 = 0 Factor
(z - 25)(z + 16) = 0 Put the x^2 back in
(x^2 - 25)(x^2 + 16)
======================
Factor x^2 - 25 using the difference of squares.
(x^2 - 25) = (x + 5)(x - 5)
x = +5 and x = - 5
======================
Factor x^2 + 16
x^2 + 16 = 0
x^2 = - 16 Take the square root of x^2 and -16
x = sqrt(-16)
x = +4i, x = - 4i
Answer
The roots are +/- 5 and +/- 4i
Answer:
8x + 29 < 17
Step-by-step explanation:
Let the unknown number be x .
According to the question ,
8 times x when added to 29 will give a sum less than 17 .
So , we can write
8x + 29 < 17.
We can also solve it
so we will get
8x < -12
x<-1.5.
