Answer:
1) 
2) 
3) 
4) 40
5) 
Step-by-step explanation:
1) Distribute the negative sign that is outside the parentheses and then you must add like terms, as following:

2) According to the Product property of exponents, when you multiply powers with the same base, you must add the exponents. Then:

3) Apply the Distributive property and the Product property of exponents. Then, you obtain:

4)
is a square of a sum, then, by definition you have:

Then:

The coefficient of the second term is the number in front of the variable <em>a.</em> Then, the answer is: 40
5) Apply the Distributive property and the Product property of exponents, then, oyou must add the like terms:

The answer is : x= -y/3+2
A. true, the median of a data set is less resistant to outliers than the mean
Area of the larger square = 12² = 144 cm²
Area of the smaller square = 7² = 49 cm²
Area of the section = 144-49 = 95 cm²
9514 1404 393
Answer:
y = 12
Step-by-step explanation:
The angle bisector divides the sides of the triangle proportionally. This tells us ...
y/6 = 8/4
y = 6(2) . . . . . multiply by 6
y = 12
