2x+5=25
2x=25-5
2x=20
X=20/2
X=10
570 is the answer. since 1000 has 3 zeroes on the end of it, you take the decimal point and move it 3 spots to the right.
Answer:
x = 12
Step-by-step explanation:
5x - 17 = 43
5x = 43 + 17
5x = 60
x = 60 : 5
x = 12
There are 12 such shapes. One can start with two squares, adding squares around the edge and rejecting shapes that have been previously seen. Repeating until you have 5 squares results in 12 distinct shapes.
