(3x² + 5xy - 2y²)
3x² + 5xy - 2y² (rewrite the expression) (write 5xy as a difference)
3x² + 6xy - xy - 2y² (factor the expression) (factor out 2x from the expression)
3x x (x + 2y) -y x (x + 2y) (factor the expression) (factor out x + 2y from the expression)
Solution : (x + 2y) x (3x - y)

15 - 4j = 43
Help me
Answer:
I did not understand your question so this is what I know. If it is correct pls mark me brainliest.
Step-by-step explanation:
15 + -4j = 0
Solving for variable 'j'.
Move all terms containing j to the left, all other terms to the right.
Add '-15' to each side of the equation.
15 + -15 + -4j = 0 + -15
Combine like terms: 15 + -15 = 0
0 + -4j = 0 + -15
-4j = 0 + -15
Combine like terms: 0 + -15 = -15
-4j = -15
Divide each side by '-4'.
j = 3.75
Simplifying
j = 3.75
The solution of the linear equation with single variable 15 - 4j = 43 will be negative 7.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation with a single variable 'j' is given below.
15 - 4j = 43
Simplify the equation, then the value of the variable 'j' will be calculated as,
15 - 4j = 43
-4j = 43 - 15
j = 28 / (-4)
j = - 7
The arrangement of the direct condition with a single variable 15 - 4j = 43 will be negative 7.

The Ruiz family is exchanging euros for US dollars. The exchange rate is 1 euro equals 1.35261 USD. Since the Ruiz family knows that USD are stated to the nearest hundredth of a dollar, they used the conversion ratio
Answer:
It will depend on how many euros they intend to convert. If they were only converting one euro they would get $1.35 whichever rate they used, but imagine it was a thousand euros - at the correct rate they would get $1352.61, at the proposed rate they would only get $1350. No, by rounding the conversion ratio, the Ruiz family will not be getting the most accurate answer. Using the more accurate conversion ratio will give an answer with more than 2 decimal places so the answer can accurately be rounded after the conversion.

Drag the expressions to the correct functions. Not all expressions will be used. Consider the functions f and g. f(x)=4x^2+1 g(x)=x^2-3 Perform the function compositions.
Answer:
(f o g)(x) = 4x⁴ - 96x + 37
(g o f)(x) = 16x⁴ + 8x² - 2
Step-by-step explanation:
Since, the given functions are,
f(x) = 4x² + 1
g(x) = x² - 3
(f o g)(x) = f[g(x)]
f[g(x)] = 4(x² - 3)² + 1
= 4(x⁴ - 24x + 9) + 1
= 4x⁴ - 96x + 36 + 1
= 4x⁴ - 96x + 37
(g o f)(x) = g[f(x)]
= (4x² + 1)²- 3
= 16x⁴ + 8x² + 1 - 3
= 16x⁴ + 8x² - 2
Therefore, out of the given options only two expressions are correct.
