Answer:
21
Step-by-step explanation:
given : 2 triffles = 7
6 / 2 = 3 so miutiple both side by 3
2 x 3 = 6 and 7 x 3 = 21
6 triffles = 21
OR
Find the cost of 1 triffle:
7 / 2 = 3.5
1 triffle = 3.50
3.50 each x 6 triffles = 21
Answer: B
Step-by-step explanation:
Answer:
we have
(-x -5) to the power of 2
we know that
(-x -5) to the power of 2 = (-x -5) x (-x -5)
To multiply two binomial I can use the FOIL method
(-x -5) x (-x -5) = (-x) x (-x) + (-x) x (-5) + (-5) x (-x) + (-5) x (-5)
= X to the power of 2 + 5x +5x + 25
= x to the power of 2 +10x +25
therefore
the answer is
the missing coefficient of the x-term is 10
