Consider the two expressions. Expression 1
7k+2k−1
Expression 2
4k(2)−1

Which statement is true?

a. The two expressions are equivalent because they both simplify to 6k−1

b. The two expressions are equivalent because they both simplify to 8 k .

c. The two expressions are not equivalent because they have the same value when any value is substituted for k

d. The two expressions are not equivalent because they do not always have the same value when any value is substituted for k

cosine

step-by-step explanation:

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8  

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .
