What is an expression?
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.
The expression 7x = 42 for the value of x will be solved as below:-
7x = 42
x = 42 / 7
x = 6
Therefore, the value of x will be equal to 42.

C. $97.20
Step-by-step explanation:
Let the dinner bill be $x.
The tip given to the waiter is $14.58.
Also, it is given that the tip is 15% of the tip.
Thus we get the relation 15% of x = 14.58
i.e. 0.15x = 14.58
i.e.
i.e. x = 97.20
Hence, the amount of dinner bill before the tip is added is given by $97.20
the amount of the bill before the tip = 14.58 *100 /15 = 97.20 $

The unit rate of 600 miles in 7 hours is 85.71 miles per hour.
Given that, distance= 600 miles and time= 7 hours.
What is the unit rate?
Unit rate can be defined as the ratio between two measurements with the second term as 1. It is considered to be different from a rate, in which a certain number of units of the first quantity is compared to one unit of the second quantity.
Here unit rate is
Speed =Distance/Time
= 600/7
= 85.71 miles per hour
Therefore, the unit rate of 600 miles in 7 hours is 85.71 miles per hour.

Answer:
you cant solve it, since we need and = sign and other numbers on that side,
but you can simplify it to (x^2+4x+4)
Step-by-step explanation:
x^3+6x^2+12x+8/x+2
=(x+2)(x+2)(x+2)/x+2
=x^2+4x+4, since you cancel out one of the numerators(x+2) with the denominator

The graph of the function is attached to the solution.
The given equation is f(x) = x²+5, the power on the variable is 2, that means the equation is a quadratic equation therefore, the graph will be a parabola,
Since, there is no negative sign so, the parabola will be opened up,
Also, there are 5 units added in the equation that mean the parabola will be 5 units up from the origin.
So, the graph will be an upward opened parabola with its vertex at (0, 5)
