Answer:
The correct option is:
2, 4, 12, 48, 240
Step-by-step explanation:
We have to determine the first 5 terms of the sequence by using following formula:
To Calculate the first 5 terms.
Put n = 1
a₁ = 2 (1)!
a₁ = 2(1)
a₁ = 2
Put n = 2
a₂ = 2 (2)!
a₂ = 2 (2·1) = 2(2)
a₂ = 4
Put n = 3
a₃ = 2(3)!
a₃ = 2(3·2·1)
a₃ = 2(6)
a₃ = 12
Put n = 4
a₄ = 2(4)!
a₄ = 2(4·3·2·1)
a₄ = 2(24)
a₄ = 48
Put n =5
a₅ = 2(5)!
a₅ = 2(5·4·3·2·1)
a₅ = 2(120)
a₅ = 240
The answer to this question has to be 9
Answer:
Addition Property of Equality
Step-by-step explanation:
we know that
The<u><em> Addition Property of Equality</em></u> states that if you add the same number to both sides of an equation, the sides remain equal
In this problem we have
a=b
a+5=b+5 -----> by addition property of equality
I’m going to use the second one to explain
-8j + 14 = -2(4j-7)
So you distribute -2 into the parentheses on the right side, and you get -8j + 14, which is the same as the left side. Therefore, it is a true statement. It turns from a - to a + because it is two negative numbers multiplying by each other.
Answer:
x=12 ; y=8
Step-by-step explanation:
8x+13=11x-23(2 opposite side of a parallelogram is equal)
move the x terms to the left side.
8x-11x=-23-13
-3x=-36
3x=36
x=12
2y+12=4y-4(2 opposite side of a parallelogram is equal)
move the y terms to the left side
2y-4y=-4-12
-2y=-16
2y=16
y=8
