(fg)(x) means to multiply the functions f(x) * g(x).
(25 - x^2)(x + 5)
25 * x = 25x
25 * 5 = 125
- x^2 * x = - x^3
- x^2 * 5 = - 5x^2
Putting it all back together:
- x^3 - 5x^2 + 25x + 125

Answer:

12πx⁴, 15x⁷, 16x⁹

Step-by-step explanation:

Volume of a cylinder: πr²h

Volume of a rectangular prism: whl

Plugging in variables for the volume of a cylinder, we get: 3x²·(2x)²·π

3x²·(2x)² = 3·2·2·x·x·x·x

= 12·x⁴

=12x⁴

Now, we just multiply that by π.

12x⁴·π = 12x⁴π

A monomial is a 1-term polynomial, so 12x⁴π is a monomial.

Plugging in variables for the volume of a rectangular prism, we get: 5x³·3x²·x²

5x³·3x² = 5·3·x·x·x·x·x

= 15·x⁵

= 15x⁵

Now, we just multiply that by x².

15x⁵·x²

= 15·x·x·x·x·x·x·x

= 15·x⁷

=15x⁷

A monomial is a 1-term polynomial, so 15x⁷ is a monomial.

Same steps for the last shape, another rectangular prism:

2x²·2x³·4x⁴

2x²·2x³

= 2·2·x·x·x·x·x

= 4·x⁵

= 4x⁵

Now, we just multiply that by 4x⁴.

4x⁵·4x⁴

= 4·4·x·x·x·x·x·x·x·x·x·

= 16·x⁹

= 16x⁹

A monomial is a 1-term polynomial, so 16x⁹ is a monomial.

I need help with this math question. What is the Area of this shape?
zubka84 [21]

Answer:

A=174

Step-by-step explanation:

Step 1: Separate the figure into two separate shapes, a triangle and a square

Step 2: Find the dimensions of the triangle and square.

Square - l=12 w=12

Triangle - h=5, b=12. (The height was found by subtracting the length of the square (12) from the total length (17).

Step 3: Solve by using formulas

A=(5)(12)/2=30

A=12*12=144

Step 4: Add the parts together

144+30=174

A=174
