Answer:
f(2) = 28
Step-by-step explanation:
f(2) = 2(2³) - 18(2²) + 36(2) + 12
= 2(8) - 18(4) + 72 + 12
= 16 - 72 + 72 + 12
= 16 + 12
= 28
Two brothers have a total age of 28 if one brother is older by 20 years how old is the second brother
Answer:
8
Step-by-step explanation:
Total meaning addition, you would use the opposite operation to find the answer.
28 - 20 = 8
And to check your work you would add;
20 + 8 = 28
which is the brothers total combined age.

Step-by-step explanation:
Let $f(x) = x^3 + 3x ^2 + 4x - 7$ and $g(x) = -7x^4 + 5x^3 +x^2 - 7$. What is the coefficient of $x^3$ in the sum $f(x) + g(x)$?
Answer:
6
Step-by-step explanation:
Adding the two polynomials gives
(x^3 + 3x^2 + 4x - 7) + (-7x^4 +5x^3 + x^2 - 7) =
-7x^4 + (x^3 + 5x^3) + (3x^2 + x^2) + 4x + (-7-7) =
- 7x^4 + 6x^3 + 4x^2 + 4x -14
The x^3 term is 6x^3, so the desired coefficient is 6.

A can of paint is a right circular cylinder. The radius of the base is 5 centimeters and the height is 12 centimeters. Find the number of cubic centimeters of paint, in terms of π, contained in a full container.
Answer:
The answer is 300
The number of cubic centimeters of paint contained in the full jar container is n = 300 and the volume is V = 300π cm³
What is a Cylinder?A cylinder is a three-dimensional shape consisting of two parallel circular bases, joined by a curved surface. The center of the circular bases overlaps each other to form a right cylinder. The volume of a cylinder is
Volume of Cylinder = πr²h
Surface area of cylinder = 2πr ( r + h )
where r is the radius of the cylinder
h is the height of the cylinder
Given data ,
The volume of a right circular cylinder can be calculated using the formula:
V = πr²h
where V is the volume, r is the radius of the base, and h is the height.
Substituting the given values, we have:
V = π(5 cm)²(12 cm)
V = π(25 cm²)(12 cm)
V = 300π cm³
Hence , a full container of paint contains 300π cubic centimeters of paint.

Helpshshdhdgdghseyeydgd
Answer:
To round 17.126 to the nearest tenth consider the hundredths’ value of 17.126, which is 2 and less than 5. Therefore, the tenths value of 17.126 remains 1.
17.126 rounded to the nearest tenth = 17.1
The following table contains starting numbers close to 17.126 rounded to the nearest 10th.

Answer: 30 degrees
Step-by-step explanation:
The total is 180 degrees.
there is a right angle on the left. A right angle is 90 degrees.
180 - 90 = 90
There is still 90 degrees left, meaning that the right side is a total of 90 degrees.
2x + x = 3x
x = 90/3
x = 30
Therefore,
x = 30 degrees!
