Answer: c. 50
Step-by-step explanation:
You just line it up I think
<span>The perimeter of a rectangle is:
P = 2(l + w)
So we have:
P = 2(l + x)
This is one of our expressions.
It says the length is 3 times the width.
So we have 3 * x or 3x.
We can write:
l = 3x
Now plug this into the formula:
P = 2(l + x)
Plug in '3x' for 'l'</span>
Answer:
The first step to solving the equation is:
Hence, 3x + 24 = 42 is the correct option.
Step-by-step explanation:
Given the equation
First of all, we need to apply the distributive law on the left side of the equation to expand the equation.
So the equation would be expaneded using the distributive law on the left side of the equation
∵ a(b+c) = ab + ac
Therefore, the first step to solving the equation is:
Hence, 3x + 24 = 42 is the correct option.
1.
A graph is formed by plotting all pairs (x,y), such that y is f(x), for a certain function f.
for example:
Take a look at the graph. (x, y)=(3, 5) is on the graph. This means that f(3)=5 (because f(x)=y)
2.
The real solutions of a function f, are those points x, such that f(x)=0.
in the graph we see no point (x, 0), so there are no real solutions.

Answer:
640 bacteria.
Step-by-step explanation:
Make a chart.
Bacteria Weeks
40 0
80 1
160 2
320 3
640 4
It starts off with 40 bacteria, which means no weeks have passed so far. That is why 40 pairs with 0 rather than 1.
