b. Chelsea’s solution was incorrect because if you add all the angles up you only get 175 and a triangle measures 180 degrees. .
Answer: 7cm
Step-by-step explanation:
The perimeter of a triangle is calculated by adding the length of the 3 sides together. Let the third side be x , then
x + 9 + 6 = 22
x + 15 = 22
Subtract 15 from both sides , that is
x = 22 - 15
x = 7
Therefore : the third side is 7cm
6+2y, since the tree is already 6 feet, it grows 2 feet per year so you add 2 feet to the 6 feet every year
15x is greater than or equal to 525
the answer is X is greater than or equal to 35
I'm pretty sure it's
3.648 x 10(exponent 3)
