Answer:
f(-9) = 279
Step-by-step explanation:
f(x) = 4x^2 + 7x + 18
f(-9) = 4(-9)^2 +7(-9) + 18
= 4(81) - 63 + 18
= 324 - 63 + 18
= 279
Having the square root of 25 * sqrt2 is more helpful because you know that the square root of 25 is 5, so the expression simplifies to become 5 * sqrt2, or 5sqrt2.
Answer:
The answer will be 1/4 , 1/2 , 2/3 , 3/4
First, find the common denominator.
12 is the smallest number that 4, 2, and 3 go into.
3/4 = 9/12
1/2 = 6/12
1/4 = 3/12
2/3 = 8/12
Now you can put them into order.
I am really sorry if it is incorrect
Given:
The expression is 
.
To find:
The domain of the expression.
Solution:
We have,
We know that, the square root is defined for only non-negative values. So,
Divide both sides by 6.
Thus, the value of variable less than 
make any sense.
Therefore, the domain of the given expression is ![(-\infty,\dfrac{2}{3}]](https://tex.z-dn.net/?f=%28-%5Cinfty%2C%5Cdfrac%7B2%7D%7B3%7D%5D)
