Question

The sides of an isosceles triangle have lengths 3x-1, -2x+29. The base has length 4x+5. What is the length of the base?

Answer 1

help please!

Answer 2

the congruent legs are 3x-1 and -2x+29

Answer 3

so

3x-1 = -2x+29

solve this for x

Answer 4

once you have x, use it to find 4x+5

Answer 5

That's how i thought you solve it, but each time i try to solve for x i get 3x=28 but if you divide28 by 3 you get a decimal, what am i doing wrong?

Answer 6

3x-1 = -2x+29

3x-1+2x = -2x+29 +2x

3x+2x -1 = 29

3x+2x -1+1 = 29+1

3x+2x = 29+1

I'm sure you see where you went wrong at this point

Answer 7

i see where i went wrong i forgot to write the x on -2 so the answer is 29(:

Answer 8

yes because x = 6

base = 4x+5

base = 4*6 + 5

base = 24+5

base = 29 units
