Answer:
18
Step-by-step explanation: Each side on a square its the same to the other one, so 72 divided by 4 its equal to 18
<span>From the problem, you can get this equation:
Jane is 2 years older than Sally
J=z+2
David is 4 times older than Jane.
D=4J
</span>Write two equivalent expressions that represent David’s age in terms of Sally’s age, z, and explain how the two expressions relate to one another.<span>Sally is z years old.
From the 2 equation above, you can get:
</span>D=4J
D=4(z+2)
D=4z+8
D-8=4z
(D-8)/4=z
The two equivalent expression would be D=4z+8 and (D-8)/4=z
The expression that more usefull would be D=4z+8 if you want to determine David age.
You can write it in two types of fractions:
1) ur answer will be 26 and 2/10 which can be simplified to 26 and 1/5
2) ur answer will be 262/10 which can be simplified to 131/5
The first is the more recommended way of writing your answers.
Answer/Explanation:

Without the expressions given, answer by referencing these steps.
4 = 4/1
When multiplying fractions, multiply both numerators and both denominators to get the answer.
In the answer, you may simplify if there are common factors in both the top and bottom number. In this case, 12 and 5 do not have a common factor and is already in the most simplified form.
