The lengths in cm, of the sides of a triangle are 3x - 5, 2x-1 and x+1 3x - 5
2x - 1
(a) Write down an expression, in terms of x, for the perimeter of the triangle
(2)
The perimeter of the triangle is 31 cm.
(b) Work out the value of x.

a) p = 6x - 5

b) x = 6

Step-by-step explanation:

a) p = a + b + c

p = 3x - 5 + 2x - 1 + x + 1

p = 6x - 5

b) p = 6x - 5 =31

6x - 5 = 31

6x = 36

x = 6

step-by-step explanation:

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
