Answer:
Fourth option: (x-4)(x+4)
Step-by-step explanation:
x^2-16
Using a^2-b^2=(a-b)(a+b) with:
a^2=x^2→sqrt(a^2)=sqrt(x^2)→a=x
b^2=16→sqrt(b^2)=sqrt(16)→b=4
Then:
x^2-16=(x-4)(x+4)
Answer:
The number of zero pairs that will be added to the board is
✔ 4
The equivalent factored form of x2 – 16 is
✔ (x – 4)(x + 4) (D)
.
Answer: A
Step-by-step explanation:
and losses is sorted by number of points scored.
> 40 points <40 points Total
Win 18
11
29
Loss 2
9
11
Total 20
20
40
Which of the following is the best evidence of an association between scoring
40 points or more and the rugby team winning a game?
The best evidence is given when scoring 40 points or more in a game, the Bimini team won more games (18/20) than when scoring fewer than 40 points (11/20).
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
The rugby squad from Bimini High School won the state title that year. A record of their wins and losses is shown, in which the relationship between wins and losses is sorted by the number of points scored. From observation, The best evidence is given when scoring 40 points or more in a game, the Bimini team won more games (18/20) than when scoring fewer than 40 points (11/20).
Thus, the best evidence is given when scoring 40 points or more in a game, the Bimini team won more games (18/20) than when scoring fewer than 40 points (11/20).

Answer:
The Bimini team won a high proportion of games when scoring 40 points or more (18/20) compared with when they scored less than 40 points (11/20).
A. GDP
B. CPI
C. Unemployment rate
The "Economic-Indicator" which measures inflation is the : (b) Consumer Price Index (CPI).
The CPI tracks the average price changes of a basket of goods and services over time, reflecting the cost of living for consumers. It measures the inflation rate by comparing the price changes of this basket of goods and services from one period to another.
By tracking CPI, economists and policymakers can assess general level of price inflation in an economy. GDP (Gross Domestic Product) is a measure of the total value of goods and services produced in an economy, while unemployment rate reflects percentage of labor force that is unemployed and actively seeking employment, which is not directly related to measuring inflation.
Therefore, the correct option is (b).

An expression that combines numbers and operations is a mathematical statement that represents a calculation or computation.
An expression can involve various arithmetic operations such as addition, subtraction, multiplication, division, exponentiation, and more.
Here are some examples of expressions:
Addition: 5 + 3
Subtraction: 10 - 2
Multiplication: 4 × 6
Division: 20 / 5
Exponentiation: 2³ (2 raised to the power of 3)
Combination: (5 + 3) × 2
In the last example, the expression combines addition and multiplication. Parentheses can be used to indicate the order of operations, ensuring that calculations are performed correctly according to mathematical conventions (e.g., multiplication before addition).
