Answer:

(n-7) (n+6)

Step-by-step explanation:

1. You need to find two numbers that's product will equal to 42 and it's sum is -1.

2. You could probably figure out it's 7 & 6 by now and now you have to figure out which one is positive or negative since they both can't be positive or negative since the product needs to be negative and if it will come out to -1. It's simple math from -7 + 6 equals -1. So the 7 would be negative in the equation and the 6 would be positive.

Anna‘s age is eight years less than four times her sisters age right in expression for Anna‘s age how old is Anna if her sister

mixer [17]

Anna's age will be equal to 6 years if her sister is five years old. The expression is Anna= 2T -4.

<h3>What is an expression?</h3>

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Anna‘s age is eight years less than four times her sister's age right in expression for Anna‘s age how old is Anna if her sister is five years old

The expression for Anna's age is given below:-

Anna's age= 2T-4

Sister = 5 years

Anna= 2T -4

T is my sister's age. Then Anna's age will be calculated as:-

2(5)-4 = 10 - 4 = 6 years

Therefore, Anna's age will be equal to 6 years if her sister is five years old. The expression is Anna= 2T -4.

Given the function f(x) = 2x − 1 and the linear function g(x), which function has a greater value when x = 3?

garik1379 [7]

Answer:

The function g(x) has a greater value when x = 3. The function g(x) will be 7 when x = 3 while the function f(x) is will be 5

Step-by-step explanation:

For the function f(x), when x = 3, you get the equation f(x) = 2(3) - 1. Two times three equals six, so the equation can be simplified to f(x) = 6 - 1. Six minus one equals five, so f(x) = 5 when x = 3.

For the function g(x), when x = 3, you get the equation g(x) = 4(3) - 5. Four times three equals 12, so the equation is now g(x) = 12 - 5. 12 minus five equals seven, so g(x) = 7 when x = 3.

Hope this helps :)
