Answer:
I am not so sure but if I were to choose it went up from an 200% increase.
Step-by-step explanation:
The pythagorean theorem states that the sum of two legs to the 2nd power is equivalent to the hypotenuse to the 2nd power (
) . Do note that the pythagorean theorem only works with right triangles.
Answer:
n=6/4
Step-by-step explanation:
-4(-6-2n)=30+8n
24+12n=30+8n
-24 =-24
12n=6+8n
-8n = -8n
4n=6
n=6/4
The ladder must be 9.4 ft to reach the top of the building
Here, we want to get the length of the ladder that will reach the top of the building
Firstly, we need a diagrammatic representation
We have this as;
As we can see, we have a right triangle with the hypotenuse being the length of the ladder
We simply will make use of Pythagoras' theorem which states that the square of the hypotenuse is equal to the sum of the squares of the two other sides
Thus, we have;
Answer:

Step-by-step explanation:
Given

(a): Write as additive inverse.
An additive inverse is of the form a + (-b)
In this case:


So, the expression can be represented as:

(b): Number line representation
When the expression in (a) is solved.
The result is:

This means that the number line must accommodate 7 and -1.
Having said that, options (b) and (c) are out because their range is 0 to 15 and this excludes -1.
Option (d) is a wrong representation of 
Hence, (a) is correct
