divide by 2=7
Answer:

Step-by-step explanation:
This can be simplified by combing like terms.
8x^2 and 15x^2 are like terms. Since both numbers are positive, we add them together.
The sum of 8x^2 and 15x^2 is 23x^2
I hope this helps.
Answer:
f(3) = 10
Step-by-step explanation:
f(x)=-x^2+19
Let x= 3
f(x)=- (3)^2+19
= -9 + 19
= 10
So first, let's calculate the total volume of all metal spheres.
Total volume = number of spheres * 4/3* πr³
Total volume = 24*4/3*3.14*4³ = 6430.72 cm³
Now, let's equate this to the volume of the rectangular prism. The volume of a rectangular prism is:
V = LWH, where L is the length, W is the width and H is the height
Thus,
6430.72 = (6 cm)(2 cm)(H)
Solving for H,
<em>H = 535.9 cm</em>
