Answer:
B
Step-by-step explanation:
Area of a triangle is 1/2 * Base * height
So we can say: 1/2 * k * (k-2)
That is equal to 24. Let's solve for k first:

Putting 8 into k, solves the equation, hence k is 8.
<em>So point P (8, 8- 2) , which is </em>
<em>P(8,6)</em>
<em />
The slope of OP is the change in y divided by change in x. Looking at the diagram, going from (0,0) to (8,6), the change in y is 6 and change in x is 8
So slope is 6/8
Reduced, that is 3/4
Answer choice B is right.
The correct answer is none of the ones listed. The correct answer is 18/5.
In order to find this, follow the order of operations.
−(−2−5x)+(−2)=18 ---> Distribute the negative
2 + 5x - 2 = 18 ----> Combine like terms
5x = 18 -----> Divide by 5
x = 18/5
Note: <em>It seems you mean a piece of string is 3.5 long. So, I am assuming that a piece of string is 3.5 cm long.</em>
Answer:
140 cm of the original piece is left after Joe cuts three pieces.
Step-by-step explanation:
Given the piece of string
As we know that
so the length of a piece of string = 350 cm
As joe cuts three pieces from it, and each 70 cm long.
so the total length of three pieces which were
cut by joe = 70cm + 70cm + 70cm = 210 cm
So, subtracting the total length of the three pieces that were cut from the total length of the string:
350 cm - 210 cm = 140 cm
Therefore, 140 cm of the original piece is left after Joe cuts three pieces from it.
