also between 12/8 and 18/12 is 15/10
She could write 18 is a multiple of 9 but im nt sure if that answer is correct
Answer:
The left side 5
The bottom 10
The slanted side 11
Step-by-step explanation:
To find the perimeter of the triangle, add up the side lengths
x+ 2x+1 + x+5 = 26
Combine like terms
4x+6 = 26
Subtract 6
4x+6-6 =26-6
4x=20
Divide by 4
4x/4 = 20/4
x=4
The left side x = 5
The bottom x+5 = 5+5 = 10
The slanted side = 2x+1 = 2*1 +1 = 10+1 =11
a(n) = 6n - 7
a(12) = 6(12) - 7
a(12) = 72 - 7
a(12) = 65
The answer is B.
