Since each point of the triangle is going to be 1.5 times as far from the center of dilation, each side will increase by a factor of 1.5..

3 x 1.5 = 4.5m
4 x 1.5 = 6m
5 x 1.5 = 7.5m

So the perimeter of the new triangle will be 4.5 + 6 + 7.5 = 18 meters

1/8 is it greater or lesser than 1/4

Answers

1/8 is less than 1/4 because when it comes to solving this kind of problem (with fractions) if the numerators(the top numbers) are the same, the fraction with the higher denominator , is going to be less. Hope this helps! :)
Example: 1/2 is greater than 1/4.

for this question you should know that 1/4 is equal to 2/8 so now you can see that 1/8 is less than 2/8 so 1/8 is less than 1/4 :)))

X 9.2 13.8 can someone show me how to solve this

Answers

to solve for x try moving everything else to the otherside
in x - 9.2 = 13.8
there is a - 9.2 so to move it to the other side you add 9.2 to both sides of the equation
x -9.2 +9.2 =13.8 +9.2
the 9.2 cancel each other out which leaves
x = 13.8 +9.2
then you just add 13.8 +9.2 to find what x equals

x - 9.2 = 13.8

Take 9.2 to the other sides to isolate x

x - 9.2 +(9.2) = 13.8 + 9.2
9.2 and 9.2 cancels out

x = 23
