Add 8.1 to both sides to find x!
hope this helps :-)
Answer:
A. 40.18
B. 42.80
Step-by-step explanation:
A. To find the discount price of an item multiply the price by the percentage you pay. Its discounted 20% meaning you pay 80%. Then the price of the coat is 0.8(50.22) = 40.18.
B. The sale price of a shirt is 25.68. The original price as reduced by 3/5. The original price is equal to 25.68 = 3/5x. Solve for x by multiplying by the reciprocal. 25.68 ( 5/3) = x. 42.8 = x.

Answer:

Step-by-step explanation:
The polynomial given for simplification is:

Now, we combine like terms using the commutative property of addition.
The commutative property of addition states that:

So, the order can be shuffled when we add terms.
The terms containing 't' are grouped together and the constant terms are grouped together. This gives,

Now, we group them using associative property and converse of distributive property as:

Simplifying the above expression, we get:

Therefore, the simplified form is 
A²+b²=c²
39²+b²=89²
1521+b²=7921
subtract 1521 from both sides
b²=6400
so then you square both sides
√6400
80
