Answer:
The expression has two variables x and y.
Step-by-step explanation:
<u>What is a variable?</u>
A variable is a letter, for instance or , that represents an unknown number.
Given the expression
The given expression has three terms which are x, 4y, and -9.
Here:
- The term 'x' is the unknown variable x.
- The term '4y' has a coefficient (the number next to a variable y) of 4.
- The term '-6' is a constant.
As we already know that a variable is a letter, for instance x or y, that represents an unknown number. In other words, the values of x, or y are unknown to us.
Thus, the expression has two variables x and y.

Step-by-step explanation:
A: (2³)² ÷ 2^5 = 2
B: 4^0 = 1
C: 3^(4-5) = 3^-1 = 1/3
D: 5^0 = 1
Answer:
7 weeks.
Step-by-step explanation:
Will works 7 hours a day, 6 days a week. So total number of hours worked by Will is,
hours
He earns £9.20 an hour, so total money earned in a week by Will will be,
As he shares with his mother in a ration of 5:2, so he gets 2 parts out of 7 parts. (as 5+2=7)
So the actual amount saved by Will is,
The price of the car is £1932, so the number of week that Will will take is,

Answer:
A. (x² -y²)² +(2xy)² = (x² +y²)²
Step-by-step explanation:
As is often the case with problems like this, the correct answer (A) is the only answer that is actually a true equation.
Choices B, C, D are only true if x or y is zero--a violation of the given condition that they are positive integers.
