Solve this k/3+4-2k=-9k

Answers

Answer 1

Answer: k/3 + 4 -2k = -9k
First you add 9k to both sides
k/3 + 4 -2k = -9k
+9k +9k
k/3 + 4 + 7k = 0

Now subtract 4 from both sides
k/3 + 4 + 7k = 0
-4 -4
k/3 + 7k = -4

Now multiply 3 by both sides
k/3 + 7k = -4
x3 x3 x3
k +21k = -12

Now add k + 21k
22k = -12

Now divide both sides by 22
22k = -12
----- -----
22 22
k = -6/11

Jenn will use 18 connecting cubes to make a model of a park. The model will be in the shape of a rectangle and will have a height of one cube. In how many different ways can Jenn make the model of the park?

Answers

This question is basically: how many different pairs of numbers multiply up to 18?

(This is a simpler form of the question because the question is just asking how many shapes of a rectangle can Jenn create with 18 blocks)

So, the numbers that multiply up to 18 are:

1 x 18
2 x 9
3 x 6

So, the answer is: Jenn can make the model of the park in 3 different ways.

Why would "-7" in the expression (x^2+3)-(x-7) become positive?(This is a genuine question not a test one)

Answers

You would use the distributive property with the negative. So the second x becomes negative, but since the 7 is already negative it becomes positive. Think of it as if you put the two dashes together you can make a plus sign.

Answer:

x is the variable that's representing a number so -7 would not become posting
