Answer:
49x+36
Step-by-step explanation:
Hey There!
for this question they would like you to simplify the expression using distributive property
To do this the first step is to distribute the 9 in to everything that is in the parenthesis
9x5x=45x
9x4=36
so now we have
45x+36+4x
the next step is to combine like terms
the only like terms in the expression are 45x and 4x so we just add the two together
45x+4x=49x
so now we have 49x+36
In conclusions the simplified version of that expression is 49x+36

Answer: 20% discount</h3>
Work Shown:
amount saved = 84-67.20 = 16.80 dollars
Divide this over the original larger price to get 16.80/84 = 0.20 = 20%
Note how 20% of 84 = 0.20*84 = 16.80 to help check the answer.
Or we can say 0.80*84 = 67.20 which also helps confirm the answer.
The 0.80 is from the fact that you save 20% but still have to pay the remaining 80%
Answer:
75%
Step-by-step explanation:
First we can solve the area of the rectangle originally the answer is:
4 × 2 = 8
Then we decrease both measurements by 50% to get the dimensions 1 and 2. The new area will be 1 × 2 which is 2.
2 is 25% of 8 which means that the area of the rectangle has been reduced by 75%.
