8x^4 + 2x^2 - 45 = (2x^2 + 5)(4x^2 - 9) = (2x^2 + 5)(2x + 3)(2x - 3)
(a) 2x^2 + 3....no
(b) 2x^2 + 5...yes
(c) 2x - 3....yes
(d) 4x^2 - 9)...no...not when it is fully factored
Answer: You took 4 dollars from your bank account to buy a stuffed animal
Step-by-step explanation: the sentence uses taking away 4 which can also mean -4
2x+ y = -4 5x + 3y = -6
y= -4 -2x
substitute y=-4-2x into 5x+3y=-6
5x + 3(-4-2x) = -6
5x -12 -6x =-6
-x=6
x=-6
sub x=-6 into 2x+y=-4
-12 + y = -4
y=8
x=-6 and y=8
C.) Multiply each term in the parentheses by 14 and then add their products.
Hope this helps!
The next term is 1.4 larger than the one before it, so the appropriate choice is
_____
However, the description
also correctly describes the relationship between a1 and a2, for example. While this equation is technically correct, it is less useful to work with, so is probably not the expected answer.
