First get them all on one side
add 7x+60 to both sides
0=x^2+17x+60
now factor
what 2 numbers mutltiply to get 60 and add to get 17?
5 and 12
0=(x+5)(x+12)
set each to zero
0=x+5
-5=x
0=x+12
-12=x
the factored form is (x+5)(x+12)=0
the solutions are x=-12 and -5
Answer:
267.947 cm^{3} of gel is required to fill the plastic ball.
Step-by-step explanation:
<em>The radius of the ball is given as 4 cm.</em>
<em>The gel is filled in the plastic ball, that means the gel occupies the volume of the radius.</em>
The volume of the sphere is given by the formula,
, the R is the radius of sphere.
Thus, the volume of gel required to fill the plastic ball to make it stress ball is
267.947 cm^{3} of gel.
We use the Order of Operations here.
Parentheses
Exponents
Multiplying
Adding
Dividing
Subtracting (PEMDAS)
And if both are there, we work left to right.
In the process we multiply first, then add left to right..
So,
9 * 8 + 2 + 4
= 72 + 2 + 4
= 74 + 4
= 78.
Add them all together and multiply by 2
