Answer:
P = 10x + 4
Step-by-step explanation:
Formula to find perimeter:
P = 2(l + w)
P = 2(2x + 3x + 2)
P = 2(5x + 2)
P = 10x + 4
Pythagorean Theorem- A^2+B^2=C^2
1) 6^2+9^2= x^2
2) 36+81= 117
Square root 117 =10.82
Hope this helped :)
The combined mass of the other two rocks is just their masses added together:
