Answer:
11
Step-by-step explanation:
Rose age = 3(x-6) = 15
Rose's brothers age = x
3(x-6) = 15
3x - 18 = 15
3x = 15+18
x = 33/3 =11
Rose's brothers age = x =11
I hope im rght!!i
Answer:
30
Step-by-step explanation:
Applying Pythagoras theorem
Hypotenuse^2=base^2+perp^2
Where base=16
And hypotenuse=34
34^2=16^2+perp^2
1156-256=perp^2
Perp^2=900
Taking square root on both sides
Perpendicular=30
Well the area of the square is is 54.94^2 but the area of the circle is <span>201.06^2. I hope this helped ^^</span>
We know that an equilateral triangle has all sides equal.
Initial perimeter = s + s + s = s
Each side has been increases by then the new perimeter is:
(s+15) + (s+15) + (s+15) = 3s + 45
So the new perimeter = 3s + 45
