The correct option is B. 4(x+7) = 80.
Adding 7 to the number then multiplying it with 4 given the result 80 is shown by the equation; 4(x+7) = 80.
What is defined as the mathematical operations?Calculating a value with operands as well as a math operator is referred to as a mathematical "operation." The math operator symbol has predefined rules that must be applied to a given operands and numbers.
Operands are the numbers that are used in an operation. The operands are given different names depending on the type of operation.An operator is a symbol that represents a mathematical operation, such as:+ for addition− for subtraction× for multiplication÷ for division = equal to denotes equivalence, indicating that left hand side value is equal to a right hand side value.Now as per the given question;
Let us assume that the given number is 'x'.
Adding 7 to this number will form; x + 7.
Now, multiplying the number resultant number with 4 gives; 4(x + 7)
Now the number formed is equal to the result 80.
Thus, 4(x + 7) = 80.
Therefore, the equation which correctly represents the given formation is 4(x + 7) = 80.

help me please, what are the like terms?
Step-by-step explanation:
Like terms are are terms whose variables (and their exponents such as the 2 in x 2) are the same. In other words, terms that are "like" each other. Note: the coefficients (the numbers you multiply by, such as "5" in 5x) can be different.
So like in your picture x and x would be like terms... your picture helps as well to identify your like terms because your like terms have the same background color to there particular rectangle.

PLEASE HELP GIVING BRAINLIEST
Answer:
see explanation
Step-by-step explanation:
x and x - 20 are adjacent angles and are supplementary , thus
x + x - 20 = 180
2x - 20 = 180 ( add 20 to both sides )
2x = 200 ( divide both sides by 2 )
x = 100
x - 20 = 100 - 20 = 80
------------------------------------------------------------
11x - 2 and 75 are corresponding angles and are congruent, thus
11x - 2 = 75 ( add 2 to both sides )
11x = 77 ( divide both sides by 11 )
x = 7
11x - 2 = 11(7) - 2 = 77 - 2 = 75
