Question

A triangle has a perimeter of 8x 7. the first side of the triangle has a length of 4x, and the second side has a length of 2x − 3. what is the length of the third side of the triangle? 14x 4 6x − 3 2x 10 x 10

2X PLUS 10

Explanation:

i GOT IT RIGHT

Hope this helps!

Answer 2

2x - 4

Explanation:

subtract the sum of the 2 given sides from perimeter for third side.

third side = 8x - 7 - (4x + 2x - 3)

= 8x - 7 - (6x - 3) ← distribute parenthesis by - 1

= 8x - 7 - 6x + 3 ← collect like terms

= 2x - 4
