Question

The area of a triangle is 16 square units. The base of the triangle is x+4. The height of the triangle is x. Find x.

Answer 1

what is the formula for finding the area of a triangle?

Answer 2

A = 1/2bh

Answer 3

so you plug in x+4 for b and x for h and set it all equal to 16 and solve for x

Answer 4

still don't know the answer.

Answer 5

can you set up the equation?

Answer 6

Im so lost ... Sorry

Answer 7

you know the area is 16, that is the A

so A = 1/2 b h becomes 16 = 1/2 b h

now you know b is x+4 and h is x so plug them in the same way

Answer 8

so x equals 8

Answer 9

why does x equal 8? I don't see it

Answer 10

You said A = 1/2 bh so if I SAY 1/2 * 8*4 that equals 16

Answer 11

if x = 8 then what is x+4 ? the equation you need to solve is:

16 = 1/2 (x) (x+4)

Answer 12

um okay Thanks anyways !

Answer 13

all right, good luck with it
sorry if I confused you, but x is not 8 here
