3. Which statement is true? A. The only factors of 3 are 3 and 1.
B. The only factors of 4 are 4 and 1.
C. The only factors of 6 are 6 and 1.
D. The only factors of 8 are 8 and 1.

A

Step-by-step explanation: 4 can be divided by 2, 6 can be divided by 3, and 8 can be divided by 4. 3 can only be divided by 3 and 1, so the answer is A.

Hope this helps :)

A) 3 is a prime number which means its only factors are itself and one

Step-by-step explanation:

all other options are composite numbers and have 3 or more factors:

factors of 4: 1,2,4

factors of 6: 1,2,3,6

factors of 8: 1,2,4,8

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
