Y=4x^3 - (3+2x)^2 hope this helped! I wrote it out in the picture
You would first substitute -7 for m and 2 for n. It would look like this: 4| -7-2 | . we first solve the absolute value because it is the first step in PEMDAS or order of operations. -7-2 is equal to -9. Our equation should look like this now: 4 |-9| . we solve the absolute value portion, the absolute value of a negative number is the the same number but positive. the absolute value would be 9. (we just take the negative symbol off). we now have 4 x 9. This is equal to 36.
36 is the answer.
For this case we have that by definition the area of a rectangle is given by:
Where
- <em>w: width of the rectangle
</em>
- <em>l: length of the rectangle
</em>
The area of the original rectangle is given by:
The area of the new rectangle is given by:
Therefore, the original area increases with a factor of 9.
Anwer:
the original area increases by a factor of 9.
Answer:
B
Step-by-step explanation:
Given
f(x) = 3(x + 1)(x - 7) ← expand the factors using FOIL
= 3(x² - 6x - 7) ← distribute the parenthesis
= 3x² - 18x - 21 → B
Answer: 11
Step-by-step explanation:The given expression is:
=
=
=
Substituting the value of b=-2 in above expression, we get
=
=
=
Thus, the value of the given expression is -11.
