Answer:
- 7x^2 + 3xy - 9y
Step-by-step explanation:
(2xy- 4x^2) - (9y + 3x^2 - xy)
Add the second polynomial:
Change all the signs in the second polynomial because it has a negative sign before the parentheses.
= 2xy - 4x^2 - 9y - 3x^2 + xy
Combine like terms:
(-4x^2 - 3x^2) + (2xy + xy) - 9y
= -7x^2 + 3xy - 9y

b. Does a12 x a4 = a8 x a8 for all values of a? Explain.
Answers
Answer:
We can use the Laws of Exponent to rewrite both sides of the equation:
Let a¹² x a⁴ = a⁸ x a⁸
⇒ a¹²⁺⁴ = a⁸⁺⁸
a¹⁶ = a¹⁶ ✅
⇒ a¹² x a⁴ = a⁸ x a⁸ is true for all values of a.
Explanation:
The equation a¹² x a⁴ = a⁸ x a⁸ is true because, on both the RHS and LHS of the equation, both terms in 'a' have exponents that when added (Law of Multiplication of Exponents) are equal to each other, i.e. 12+4 = 8 + 8.

The quotient when 6.591 x 10⁷⁶ is divided by 8.45 x 10² is 6.591 x 10⁷⁴.
What is quotient?In arithmetic, a quotient is a quantity produced by the division of two numbers.
Given is to find the quotient of 6.591 x 10⁷⁶ and 8.45 x 10².
We have to find the quotient when 6.591 x 10⁷⁶ is divided by 8.45 x 10².
6.591 x 10⁷⁶ ÷ 8.45 x 10²
(6.591 x 10⁷⁶/8.45 x 10²)
(6.591 x 10⁷⁶ ⁻ ²)
6.591 x 10⁷⁴
Therefore, the quotient when 6.591 x 10⁷⁶ is divided by 8.45 x 10² is 6.591 x 10⁷⁴.

Based on the given diagram, the length of FA is 51 units
Find the diagram attached. From the diagram;
AG = 2GF
Given that:
AG = 5x + 4
GF = 3x - 1
Substitute the given parameters into the formula;
5x + 4 = 2(3x - 1)
5x + 4 = 6x - 2
5x - 6x = -2 - 4
-x = -6
x = 6
Get the FA = 5x + 4 + 3x - 1
Substitute the value of x into the expression:
FA = 8x + 3
FA = 8(6) + 3
FA = 48 + 3
FA = 51 units
Hence the length of FA is 51 units

Standard electrical voltage in Europe is 220 volts.
a. Find the impedance in a standard European circuit if the current is 22 - 11i amps.
b. Find the current in a standard European circuit if the impedance is 10 - 5i ohms.
c. Find the impedance in a standard European circuit if the current is 20i amps.
Answers
Applying the general Ohm's Law, it is found that:
a) The impedance is of 8 + 4i ohms.
b) The current is of 17.6 + 8.8i amperes.
c) The impedance is of -11i ohms.
Ohm's Law states that voltage is current multiplied by impedance, that is:
[tex]V = IZ[/tex]
Standard voltage of 220 volts, thus [tex]V = 220[/tex].
Item a:
Current is 22 - 11i amps, thus [tex]I = 22 - 11i[/tex]. Then:
[tex]V = IZ[/tex]
[tex]220 = (22 - 11i)Z[/tex]
[tex]Z = \frac{220}{22 - 11i} \times \frac{22 + 11i}{22 + 11i}[/tex]
Considering [tex]i^2 = -1[/tex]
[tex]Z = \frac{220(22 + 11i)}{605}[/tex]
[tex]Z = 0.3636(22 + 11i)[/tex]
[tex]Z = 8 + 4i[/tex]
The impedance is of 8 + 4i ohms.
Item b:
Impedance is 10 - 5i ohms, thus [tex]Z = 10 - 5i[/tex]. Then
[tex]V = IZ[/tex]
[tex]220 = (10 - 5i)I[/tex]
[tex]I = \frac{220}{10 - 5i} \times \frac{10 + 5i}{10 + 5i}[/tex]
[tex]I = \frac{220(10 + 5i)}{125}[/tex]
[tex]I = 1.76(10 + 5i)[/tex]
[tex]I = 17.6 + 8.8i[/tex]
The current is of 17.6 + 8.8i amperes.
Item c:
Current is 20i amps, thus [tex]I = 20i[/tex]. Then:
[tex]V = IZ[/tex]
[tex]220 = 20iZ[/tex]
[tex]Z = \frac{220}{20i} \times \frac{20i}{20i}[/tex]
[tex]Z = -\frac{220 \times 20i}{400}[/tex]
[tex]Z = -11i[/tex]
The impedance is of -11i ohms.
