Step-by-step explanation:
5. All like terms can be combined. There will be one term remaining after they are.
___
6. The appropriate factoring is x(x+1). This is not the same as x(2x+1).
In order to show equivalence, you need to show that the expressions produce the same result for as many different values of x as the degree of the expression plus 1. That is, you'd need to show equivalence for <em>3 different values of x</em>, as a minimum for this second-degree expression.
Answer:
Step-by-step explanation:
radius of a coin is 12 mm
Diameter of the coin is twice the radius = 2 x 12mm = 24mm
The circumference of the coin= 2πr = 2 x3.14 x 12 = 75.36m
Area of coin = πr²= 3.14 x 12 x12 = 452.16mm²
what is the area of the coin
Answer:
Step-by-step explanation:
1) y = (cos x) / x is neither, since cos x is even and x is odd. Expressions such as this are neither even nor odd. /
2) y = (sin x) / x is even, since sin x and x would either both be positive at the same time or negative at the same time. Recall that (-) / (-) is positive, just as (+) / (+) is positive.
