Perimeter of triangle = all sides added up
3a + 4 + 2a - 7 + 9a + 11

now add like terms
3a + 2a + 9a = 5a + 9a = 14a

4 - 7 + 11
= -3 + 11 = 8

so we have  14a + 8
as our simplest expression

I really need help with this
photoshop1234 [79]

Answer:

A+6+A = 20

A = 7

Step-by-step explanation:

J = number of problems Juana completed

A = number of problems Andy completed

J+A=20

J = A + 6

Replace J with A+6 in the first equation

A+6+A = 20

2A +6 = 20

Subtract 6 from each side

2A +6-6 = 20-6

2A =14

Divide by 2

2A/2 = 14/2

A = 7
