Answer:
The zeroes are 2, -2, -6, 5.
Step-by-step explanation:
If 2 of the zeroes are 2 and -2 then (x - 2)(x + 2) is factor of the polynomial.
We can now do long division.
Note (x - 2)(x + 2) = x^2 - 4, so we have:
x^2 - 4 ( x^4 + x^3 - 34x^2 - 4x + 120 ( x^2 + x - 30 <--- Quotient
x^4 - 4x^4
x^3 - 30x^2 - 4x
x^3 -4x
-30x^2 + 120
-30x^2 + 120
x^2 + x - 30 = 0
(x + 6)(x - 5) = 0
x = -6, 5.

Simple,
4x9x2.2 = volume = 79.2 cubic centimeters
79.2/1000 = 0.0792 litres
not sure if you wanted it in cubic or litres FYI if it doesn't say put the answer in cubic :)
Hello from MrBillDoesMath!
Answer:
1.5, 1.6
Discussion:
The question is how to interpret 5/10 * 3. Both multiplication and division have the same precedence but we proceed from left to right (doing the divison first)
5/10 * 3 = (5/10) * 3 = (1/2)* 3 = 3/2 = 1.5
Same approach for the second equation:
4/10 * 4 = (4/10) * 4 = 16/10 = 8/5 = 1.6
Thank you,

Answer:
or 
Step-by-step explanation:
You need to complete the square before you can take the square root of both sides.
Subtract 10 from both sides.
To complete the square, you need to add the square of half of the x-term coefficient to both sides.
The x-term coefficient is 7. Half of that is 7/2. Square it to get 49/4. Now we add 49/4 to both sides of the equation.
Now we use the square root property, if
