1. ## Two questions Help please

I think that I have the correct answer but it just seem so simple could someone double check me please. What is the perimeter of a triangle whose sides are the length of 4x,4x+7, and x=

The other question I need to right an equation and find the solution to the problem you have three buildings with the total height of 1800 ft. Building 1 is 4 times higher than building 2 and building 3 is 300ft higher than building 2. So I need the equation I would use to solve the problem

the perimeter is the sum of all the sides

Let the length of building 2 be x

then the length og building 1 is 4x

and the length of building 3 is x + 300

now can you set up an equation?

4. ## thank you One other thing

x times 4 equals building 2
x+300 = building 3

So
x+(x4)+(x+300)=1800 feet
I tried combinding like terms to solve Can you tell me if I'm on the right track

3x+300 x 4=1800
minus 300 from both sides divid by 4 then by 3 but I get 125

the buildings should be
1=250 2=1000 3=550

I cant figure out what I'm doing wrong

i don't understand what you did in the line i highlighted red

your x should represent building 2 not 1, you are reading things backwards.

anyway, we have:

x + 4x + 300 + x = 1800

=> 6x + 300 = 1800

=> 6x = 1500

=> x = 250

Thus, building 1 = 1000, building 2 = 250, building 3 = 550

6. ## thank you

I feel like an idiot I new I was on the right track but I kept staring at the problem and couldn't figure out what it was I was doing wrong. You have been a great help
