Answer:
Value of x is used to consider unknown value.
Step-by-step explanation:
Value of x is used to consider unknown value. The letter “x” is commonly used in algebra to indicate an unknown value. It is referred to as a “variable” or, in some cases, a “unknown.” In x + 2 = 7, x is a variable.
For now, we can’t get a definite answer. We can model with an equation, but we cannot find the absolute amount Jocelyn will earn, as her hourly rates are both variables. All we must do to create an equation for this is multiply the amount of hours by the rate and add. You could model like this:
25n + 15x = total amount earned
Well, you need to add together how much wood you need. one side is 4 1/4 long & the other side is 5 1/8 long. you need to find a common denominator before you add.
multiply the numerator and denominator of the first number by 2.
4 1/4 × 2 = 4 2/8
multiply the numerator and denominator of the second number by 1 because you already have common denominators.
5 1/8 × 1 = 5 1/8
now you can add.
4 2/8 + 5 1/8 = 9 3/8
9 3/8 does not simplify.
therefore Mrs. Edwards only needs to buy the smallest amount of wood available, which is 12 inches.

Answer:
the answer is
cause sin²x= 2/25
so cos²x would be 1-2/25= 23/25
then cos x is what I wrote as the answer
