A 12x+6
Combine like terms; so 7x-1x
Now it’s 2(6x+3)
Distribute 2; 2(6x) + 2(3)
Which gives you 12x+6
Would need the net to answer. but to find the answer you need to find the slant height of the square pyramid, the slant height is the hypotenuse of the right triangle formed by the height and half the base length. Use the pythagorean Theorem
Answer:
P(x) = 
- 7x² + 12
Step-by-step explanation:
Given zeros x = 2, x = - 2, x = 
, x = -
Then the factors are (x - 2), (x + 2), (x - ), (x + )
and the polynomial is the product of the factors, that is
P(x) = (x - 2)(x + 2)(x - )(x + ) ← expand in pairs using FOIL
= (x² - 4)(x² - 3) ← distribute
= - 3x² - 4x² + 12 ← collect like terms
= - 7x² + 12
I want to say D. Taking thirty coins out of the container without looking. She wants a sample not for the whole container of coins to be separated.
Answer:
no
Step-by-step explanation:
