Hello

The three different lengths are 39 as a leg 80 as a leg and 89 as the hypotneuse becasue of the Pythagoran therom. a^2+b^2=c^2
So your answers would be 39, 80, and 89

3x+2y=6and y=-3/2+5 anybody ?

nordsb [41]

This is system of equations and as such there are two methods of solving: elimination and substitution. Luckily Y is already isolated here, so in this case we just have to put in the value of y into 3x + 2y = 6

To do this we simply do:
3x + 2(-3/2+5) = 6
Distribute the 2 into the brackets
3x + -6/2 + 5 = 6
Move the 5 over and simplify the fraction
3x + (-3) = 1
Move the three over.
3x = 4
Isolate x
x=4/3

The distance between (-4,6) and (3,-7)

Akimi4 [234]

Hey there! I happy to help!

Here's how to find the distance between any two points.

Find the difference between the x values.

-4-3=-7

Square it.

-7²=49

Find the difference of the y values.

6-(-7)=6+7=13

Square that.

13²=169

Add up the two numbers you got.

169+49=218

And square root it.

√218≈14.76.

Have a wonderful day! :D

Which of the following number is 9 times the sum of its digit

vitfil [10]

Answer:

Step-by-step explanation:

9*(x + y) = 10x + y

9x + 9y = 10x + y

0 = x - 8y

8y = x

=======

y = 1

x = 8

x + y = 8 + 1 = 9

9*9 = 81

So 81 is 9 times the sum of it's digits.
