Answer:
A IS LESS THAN OR EQUAL TO 8
Step-by-step explanatiAon:
2 1/3 x 4/5
Rewrite 2 1/3 as 7/3
7/3 x 4/5 = (7 x 4) / (3 x 5) = 28/15 = 1 13/15
Write out the expression 2 - (2x-7)^2. That's it.
But if you want to go further and remove the parentheses, first expand (2x-7)^2: (2x-7)^2 = 4x^2 - 28x + 49,
and then subtract this result from 2:
2 - (4x^2 - 28x + 49) (It's important to use parentheses here)
Now, following the distributive property of multiplication, remove the parentheses:
2 - 4x^2 + 28x - 49
Combining the constants, we get the final answer: - 4x^2 + 28x - 47
Answer:
Step-by-step explanation:
The former cost of the book is
The new cost of the book is the old cost plus the of :
Since:
We have the following:
Then, the new price of the book is:
Answer: 7
Step-by-step explanation:
You can either remove brackets and just do a little addition and subtraction.
So the answer is 7.
Or just finish things inside the brackets first.
So the answer is 7.
