We are asked to find the area of the base or the side with the dimensions 4 and 2. The length would be the longest side and the width is the shorter side. The area is calculated as the product of length and width.
Area of base = 4 x 2 = 8 square units.
Therefore, the correct answer is B.
Answer:
and 
.
Step-by-step explanation:
Start by adding 1 to both sides of this equation.
.
The square of what number or numbers will lead to the number "1"? It turns out that not only 
, but 
as well. In other words, the value 
can be either 1 or -1. Either way, the equation is still going to hold. That's the reason why there are two solutions to this equation.
Consider the case when 
. Add 10 to both sides of the equation. 
.
Now, consider the case when 
. Again, add 10 to both sides of the equation, 
.
Order the two solutions in an increasing order:
- ,
- .
Answer:
-9 or negative 9
Step-by-step explanation:
The opposite of negative 9 is positive 9.
The opposite of <em>that</em> is negative 9.
Answer:
y = -2
Step-by-step explanation:
The graph passes through (0,0) and (-1,2).
The equation of a line passing through the origin is of the form,
y = mx
We now substitute (-1,2) to obtain,
2 = -m
This implies that,
m = -2
The equation is
y = -2

Answer:
kilometers per hour.
Step-by-step explanation:
We have been given an 
, which describes the number of kilometers y that a van travels in x minutes. We are asked to to find the constant speed of the van in terms of hours.
We can see that van travel 
kilometers in x hours. To find the constant speed of van, we will substitute 
in our given equation as:
Since van travels 
kilometers in one hour, therefore, constant speed of van is kilometer per hour or 
kilometers per hour.
