Answer:

9 square root of 7

Step-by-step explanation:

You’re going to break apart radical 28 into square root of 4 and square root of 7.

The square root of 4 is 2 so you add the 2 to the 3 and it equals 5 and since the square root of 7 can’t be simplified and it stays the same. So all you do is add 4 radical 7 and 5 radical 7 which equals 9 radical 7.

Radical- is square root sign

What happens to the value of the expression 150-j150−j150, minus, j as jjj decreases?

nikklg [1K]

Answer:

The value of the expression increases as j decreases

Step-by-step explanation:

Let $f(j) = 150 - j150 - j150$

$f(j) = 150 - j300$

As j decreases, the value of j300 decreases (i.e the farther j300 is from 150). Due to the wider gap between 150 and j300, the value of f(j) increases.

For example:

When j = 1, f(j) = 150 - (300*1) = -150

When j = 0.5, f(j) = 150 - (300*0.5) = 0

When j = 0. f(j) = 150 - (300*0) = 150

It is obvious from the analogy above that the expression 150-j150−j150 increases as j decreases

Please help me thank you very much. Please answer all 4 questions.

1. HI Because two parallel lines have to be on the same plane and never intersect.

2. Skew means the never intersect and they aren't on the same plane so it is GK and DH

3. Angle 3 corresponds because it is the bottom left and 7 is the bottom left.

4. 3 and 5 are same-side interior because they are both on the left side and both are inside.

Hope this helps!

write a equation 2 solve for x you are only writing the equation they said it was wrong 8x+10 12x -18 or did i do it backwards d

andrezito [222]

Answer:

x=1.25

Step-by-step explanation:

8x+10=12x-18-10=7

8x+12x=10-18+10+7

20x=25

d.b.s by 20

20x/20=25/20

1=1.25 

I thinks I am right if not pls reply me with the correct answer pls

x=1.25
