Answer:
I think you meant 40% off. If so...
Step-by-step explanation:
First, you have to turn 40 into a decimal - .40.
Then you multiply 30*.40 and get 12.
Subtract 12 from 30 since you are saving 12 dollars.
This means you spend $18 and saved $12.
So, your final answer would be $12.
Hope this helps :)
(2x-3y) (4x-y)
Multiply the polynomials using distributive property.
(a+b)(c+d) = ac+ad + bc + bd
(2x-3y) (4x-y) = (2x) (4x) + (2x)(-y) + (-3y)(4x) + (-3y)(-y)
Apply plus/minus rule.
-(-a)=a and -(a)=-a
we get
=8x²-2xy-12xy+3y²
Add like terms
=8x²-14xy+3y²
Answer: 8x² - 14xy + 3y²
Answer:
62 miles per hour/62 mph
Step-by-step explanation:
Shania drives at a CONSTANT rate, which means in the 5 hours it took her to drive, each hour she drove the same amount.
So we need to do 310 miles in 5 hours, which is:
310/5
Solving this, we get:
62
The answer is 62 miles per hour.
Happy learning!
