All three sides of the triangle have equal length.?

Question

All three sides of the triangle have equal length. What is the perimeter. One side is 9x-4 and the bottom is 2(3x+4)?

Answer 1

if all sides are equal, then:

9x-4 = 2(3x+4)

divide both sides by 2

4.5x-2 = 3x+4

+ 2 to each side

4.5x = 3x+6

- 3x from each side

1.5x = 6

divide each side by 1.5

x= 4


9 x 4 - 4 = 36 - 4
= 32

a triangle has three sides 32 x 3 = 96

The perimeter is 96

Answer 2

The wall on which the ladder is placed makes a ninety attitude with the floor, so which you would be able to prepare Pythagoras' Theorem (c^2 = a^2 + b^2, the place c is the hypothenuse). as a consequence, the ladder of length 12 feet is c. permit b = y, and a = x. Transpose the equation to form... b^2 = c^2 - a^2 whilst x = a million, y = *squareroot* (12^2 - a million^2) = *squareroot* 143 ft whilst x = 3, y = *squareroot* (12^2 - 3^2) = 3 *squareroot* 15 ft whilst x = 6, y = *squareroot* (12^2 - 6^2) = 6 *squareroot* 3 ft whilst x = 8, y = *squareroot* (12^2 - 8^2) = 4 *squareroot* 5 ft P.S. Drawing a diagram will help exceedingly. ;)

Answer 3

9x-4 = 2(3x+4)
9x - 4 = 6x + 8
3x = 12
x = 4
each side = 32
Perimeter = 32x3=96

Answer 4

96

Answer 5

so 9x-4 = 6x+8
so 3x = 12
so x=4
so sides are 32
so perimeter is 96
