Answer:
1. 6n - 15
2. x + 10
3. -4d + 15
4. true, associative property
5. distributive, commutative
Step-by-step explanation:
1. distribute 3/4 into the parentheses, so multiply 3/4 * 8 and 3/4 * -20
2. distribute the 2 into the parentheses so multiply 2 * 3x and 2 * 5, then combine like terms
3. distribute -3 into the parentheses so -3 * 4D and -3 * -5 then add like terms
4. add like terms on both sides of the equal sign and you get 10x on both sides. this is the associative property because it doesn't matter what's inside or outside the parentheses you get the same answer no matter how you add them up
5. the first part is distributive because you distributed the three into the parentheses and the second part is commutative because you switch them around and you can get the same answer

Answer:
The width of the yard is 20 ft
Step-by-step explanation:
In this particular question, we are asked to calculate the width of the rectangular front yard given the area of the front yard and the length of the front yard.
Mathematically, the area of the front yard is calculated by multiplying the length of the front yard by the breadth of the front yard.
Let’s say A = L * W
Substituting the known values, the unknown width would thus be:
W = A/L = 600 sq.ft / 30ft
W = 20 ft
