Answer: A) x + 4x = 35; 7 large stones and 28 small stones
======================================================
Explanation:
x = number of large stones
4x = number of small stones
x+4x = total number of stones = 35
x+4x = 35 is the equation to solve
-----------
Let's isolate x
x+4x = 35
5x = 35
x = 35/5
x = 7 large stones are needed
4x = 4*7 = 28 small stones are needed

Answer:
16 + 6pi cm
Step-by-step explanation:
We have a square of length 4 cm
A = s^2 = 4^2 = 16
We have 3 semi circles
with radius 2
A semi circle has an area of
1/2 pi r^2 = 1/2 pi (2)^2 = 1/2 (4pi) = 2pi
There are 3 of them
3 * 2 pi = 6pi
Add the areas together for the square and the semicircles
16 + 6pi
