Answer:
D. K+2K=51
Step-by-step explanation:
Since Lauren is 2 times Kristy's age, Lauren's age=2K
so, if the sum of the two is 51, then 2K+K=51
If you want to solve it, 2K+K=3K=51
51/3=K
17=K
34=L
The height of the pile is 150.7 mm, and the volume is V = 6,830,477.5 mm³.
<h3>
How high will be the pile of papers?</h3>
We know that each paper is 0.55mm thick, then if we pile 274 of these, the height of the pile will be:
H = 0.55mm*274 = 150.7mm
Now we want to get the volume of the pile of paper. Remember that for a rectangular prism of height H, width W, and length L, the volume is:
V = H*W*L
In this case, we have:
- H = 150.7mm
- W = 18.5 cm = 185 mm
- L = 24.5 cm = 245 mm
Then the volume is:
V = (150.7mm)*(185 mm)*(245 mm) = 6,830,477.5 mm³

Answer:
<h3>f(1)=-2.</h3>
Step-by-step explanation:
We are given a graph with four points on the graph with coordinates as following:
(-3,0)
(-2,2)
(0,1) and
(1,-2).
We need to find the value of function f(x) at x=1 that is f(1) =?
That means we need to find the y-coordinate of the point, where x coordinate is at 1.
We can see tat fourth point on the graph (1,-2) has x-coordinate at 1 and y-coordinate at -2.
<h3>Therefore, f(1)=-2.</h3>
Step-by-step explanation:
6x^3 - 9x^2=
3x^2(2x-3)
3x(x+1)−5y(x+1)=
3x-5y(x+1)
