Answer:
A. 4x²+20x+25
Step-by-step explanation:
Because of PEMDAS, you calculate the value inside of the parenthesis first, so you expand [2x+1-(4x+6)]:
2x+1-4x-6 = -2x-5.
Then apply the exponent:
(-2x-5)² = (-2x-5)(-2x-5) = 4x²+10x+10x+25 = 4x²+20x+25
Five out of ten or 1/2 depends if it is a 6-numbered die.
Answer:
¾
Step-by-step explanation:
More than 3: 9
P(more than 3) = 9/12 = ¾
Answer:
1/4 goes first
Step-by-step explanation:
To solve for the 7th term of a geometric sequence with t1 = 6 and r = 4, we use the following equation:
<span>
a(n) = a(1) r^(n-1)
a7 = (6) 4^(7-1)
a7 = 24576</span>
