Some integers are irrational is false
Answer:
b. (x+6)(x-6)
Step-by-step explanation:
x^2-36 So to get to this answer you can do two things
1. Guess and check
2. Factor it out (which is what I like to do)
In order to get x^2 you need 2xs that are positive which knocks out c and d
Then to get to -36, you need to multiply a positive 6 and a negative 6
(This was poorly explained but if you need anymore help just lmk)
Answer:
a = - 3
Step-by-step explanation:
The equation has common factors x(x + 3) on both sides
For the 2 sides of the equation to be equal, then the factor
(x + a) = (x - 3) and by comparison
a = - 3
The largest factor of 16 that is
also a perfect cube is 2. When you factor out 16, you will get 4 times 4 and
then factor out 4, you will also get 2 times 2 times 2 times 2. Other factors
for 16 is 8 times 2 which can be further divided into 2 times 2 times 2 times 2.
When you factor out 8, you get 2 times 2 times 2 and so 2 is a perfect cube.
total cards = 30 + 25 + 45 = 100
25 are basket ball
25/100 = 0.25
0.25 = 25%
25% are basketball
