The answer $1.72. you divide $24.50 by .07 and the answer comes out to $1.715 and then you round up and have 1.72
We can cosider this to be a difference of 2 squares so
4x^4 - 9x^2 = (2x^2 - 3x)(2x^2 + 3x) so D is one answer
also we could take x^2 out and get
x^2(4x^2 - 9) = C
Answer:
Answer will be 
Step-by-step explanation:
We have given the expression 
We have to simplify this expression with the help of property of exponent
According to property of exponent when there is exponent to exponenet then both the exponent are multiplied with each other
So 
Here 4 and 3 are exponent to exponent so these are multiplied with each other
If it's a square all sides are 9 feet...9x9=81
Answer:
4
