Answer: 9a^4 - b^2
= (3a^2)^2 - b^2
= (3a^2 + b)(3a^2 - b) using a^2 - b^2 = (a+b)(a-b)
hope it helps.
Answer:
I would go with A. 3(4 + 7) acres
Step-by-step explanation:
Easy, the expression is equivalent to the sum of two areas... Beans and the Squash... you just add them all together and you get 33 acres. Add the parenthesis first and then multiply by 3 you get 33
The equation would be x+7x+12x = 100
solving gives x=5
12×5=60
7×35
5+35+60=100
The age/answer is 60
First we have to find derivative of f(x):
For x=2 we have:
Now, 
Hence, the answer is A) 2
I Would say it would be the Second Graph
