Answer:
-4x - 20= -4x - 20
Step-by-step explanation:
Multiply -4 and x and -4 and 5. It has infinite solutions
X^4 - x^2 + 9 - (x^3 + 3x^2 + 12) =
x^4 - x^3 - 4x^2 - 3
Answer:
cubic units.
Step-by-step explanation:
You can use this formula for calculate the volume of a cone:

Where "r" is the radius and "h" is the height.
You know that the diameter of the base of the cone measures 8 units, then, the radius can be found by dividing the diameter by 2:

Since you already know that height and the radius, you can substitute them into the formula. Then, the volume of this cone is:


Answer:
a+4b-24
Step-by-step explanation:
4(1/4a+b−6)
=(4)(1/4a+b+−6)
=(4)(1/4a)+(4)(b)+(4)(−6)
=a+4b−24
Answer:
20% psyche test scores
Step-by-step explanation:
Given that every week, Bob plays the guitar for three hours, and his grade on each psych test is 75 percent.
