Answer:
14
Step-by-step explanation:
In an equation our aim is to find the value of what we are looking for as well as keeping the equation balanced. For example if we took away 16 only from one side then the equation would change so it's an important rule to bare in mind when solving equations, that you need to keep both sides of the equation the same.
4 ( d + 4 ) = 72
→ Expand the brackets
4d + 16 = 72
→ Minus 16 from both sides to isolate 4d
4d = 56
→ Divide both sides by 4 to isolate d
d = 14
Work shown above! Shaded region is the enclosed area
27 prime factors: 9*3 prime factors of 9: 3*3
117 prime factors: 39*3 prime factors of 39: 13*3
that would make 3 the greatest common factor. for the other ones break down the numbers into the smallest amount and see which largest factor both numbers have in common.
