1,2 and 4 beacuse the sum of two sides of the triangle is greater than third.

IRINA_888 [86]3 years ago

5 0

Step-by-step explanation:

Since the triangle inequality theorem states that the length of a side of a triangle is less than the sum of the lengths of the other two sides and greater than the difference of the lengths of the other two sides.

Upon looking at our given options we can see that option 1 and 2 are correct choices as:

1. $EF+FG>EG$

Our 1st option meets the criteria of sides of a triangle as the sum of lengths of sides EF and FG will be greater than length of third side (EG) of our given triangle EFG.

2. $EG+FG>EF$

Our 2nd option meets the criteria of sides of a triangle as the sum of lengths of sides EG and FG will be greater than third side (EF) of our triangle EFG.

Therefore, 1st and 2nd options are correct choices.

Which of the following equations is equivalent to y + 3 = -4(x - 2)?

Allushta [10]

Answer:

D. y= -4x +5

Step-by-step explanation:

The equation $y+3=-4(x-2)$ can be transformed by doing some algebra.
If we solve the second term of the equation -4(x-2)= 8 - 4x, then we have $y+3=8-4x$ (this is done by distributing the multiplication into the two terms: remember that the product of -4x(-2)=+8 because the product of two negative numbers is a possitive number).
Then, by subtracting both sides 3, we have $y=5-4x$ . Rearranging terms in the right side, we have $y=-4x+5$ , which is option D.

Quadrilateral FGHI is similar to quadrilateral JKLM. Find the measure of side JK

Stells [14]

Answer:

Heyyyy!!

The answer is 66.9

please read the explanation... it will help... I promise

Step-by-step explanation:

Okay... Here we go...

The context mentions that the two quadrilaterals are similar... meaning their sides are proportional...

So... you basically have to find the scale factor...

(the math itself is easier than the explanation...

51/16 = 3.1875 (that is the number we multiplied the sides of quadrilateral FGHI to get quadrilateral JKLM...

so to get side JK all you have to do is multiply that scale factor by side FG... which after the use of a calculator results in 66.9 (i rounded, and used a calculator... lol)

but yeah... i hope this helps...
