What is EG? (image below)
The answer of EG is 30. We can find it by Triangle Proportionality Theorem and Angle Bisector Theorem.
What is Triangle Proportionality Theorem?According to Triangle Proportionality Theorem, A triangle's other two sides are proportionately divided by a line that runs parallel to one of its sides.
So here, [tex]\frac{DN}{NG} = \frac{DM}{ME}[/tex] (Triangle Proportionality Theorem)
⇒ [tex]\frac{30}{24} = \frac{y}{12}[/tex]
⇒ 24 * y = 30 * 12
⇒ y = 15
So, we get [tex]DE = y + 12 = 15 + 12 = 27[/tex]
The angle bisector theorem states that a triangle's opposing side is divided into two halves by an angle bisector that is proportionate to the triangle's other two sides.
Now, we can find EG by Angle Bisector Theorem,
⇒ [tex]\frac{DG}{FG} = \frac{DE}{FE}[/tex]
⇒ [tex]\frac{54}{x+10} = \frac{27}{x}[/tex]
⇒ [tex]54x= 27 x + 270[/tex]
⇒ [tex]54x-27x = 270[/tex]
⇒ [tex]27x = 270[/tex]
⇒ [tex]x = 10.[/tex]
So, [tex]EG = x + x + 10 = 2x + 10 = 20 + 10 = 30[/tex].
So, finally we get EG = 30.

a positive number multiplied or divided by a negative number is always
negative or positive
Answer:
Negative
Step-by-step explanation:
Think about it this way, you cannot do something positive and then do something negative and it still be positive. You cannot do something negative and then do something positive for it to be positive. But you can do something positive and do something else positive for it to remain positive the same with negative. Therefore the answer is "negative."
Rules:
Positive ÷ Negative = Negative
Positive × Positive = Positive
Negative ÷ Negative = Positive

Answer:
35 feets
Step-by-step explanation:
Initial Position = - 25 feets
Final height reached after jumping = 10 feets
The vertical distance traveled by dolphin :
Final height reached - Initial position
(10 feets) - (-25 feets)
10 feets + 25 feets
= 35 feets

Given the sequence 31,24,17,10......
What would the 11th term of the sequence be?
The 11th term of the sequence is
Scientific Calculator
Answer:
-39
Step-by-step explanation:
This sequence follows the pattern of subtracting 7 each time. We can prove this:
31 - 7 = 24, 24 - 7 = 17, 17 - 7 = 10
So if we were to continue to the 11th term, we would subtract 7 more times.
1. 10 - 7 = 3
2. 3 - 7 = -4
3. -4 - 7 = -11
4. -11 - 7 = -18
5. -18 - 7 = -25
6. -25 - 7 = -32
7. -32 - 7 = -39
The 11th term in the sequence would be -39.

what does x equal in this equation
Answer:
x=2
Step-by-step explanation:
You have to subtract 8 from both sides.
-5x+8=-2
-8 -8
----------------
-5x= -10
now divide both sides by -5.
x=-10/-5
(And two negatives make a positive.)
x=10/5
now you have to simplify 10/5
10/5 simplified is 2
so the answer is:
x=2
