The length of the base of an isosceles triangle is x. The length of a leg is 3x - 3. The perimeter of the length is 71. Find x

8.222222222

Step-by-step explanation:

This question just means that the three sides of the isosceles triangle is 3x-3.

So it will be =3x-3+3x-3+3x-3

Firstly, you will collect like terms

Which will be =3x+3x+3x-3-3-3=9x-3

Secondly, it will be 9x-3=71

Thirdly, you will collect like terms =9x=71+3

=9x=74

Fourthly, you will divide both sides by 9

= 9x/9*74/9

=8.222222222 or 8.2 (Approximated)

answer: re

step-by-step explanation: idk buddy

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
