Answer:
The perimeter of the triangle can be expressed as 5x + 18.
Step-by-step explanation:
Perimeter of an object is the sum of the length of its sides.
For the required triangle, we have;
length of the base = x
length of the second side = 3x + 9
length of the third side = x + 9
Perimeter of the triangle = length of the base + length of the second side + length of the third side
= x + (3x + 9) + (x + 9)
= x + 3x + 9 + x + 9
= 5x + 18
The perimeter of the triangle can be expressed as 5x + 18.
Answer:
2 3/8 is the answer
Step-by-step explanation:
11/4 - 3/8
We will find the LCM of 4 and 8, which is 8.
We will do 11/4*8, which 8/4 = 2 and 2*11 = 22
Then we will do 3/8*8 = 8/8 = 1 = 3*1 = 3
So the answer will be <u>22-3 </u> = 19
8 = 8
Mixed Fraction = 2 3/8
