When solving, you will combine all your terms then divide the coefficient over.
2z+z+4z-4z+4z= 7z
7z = 0
/7 /7
z = 0
Answer:
Simplifying
(2x2 + -3x + 1)(x + -2)
Reorder the terms:
(1 + -3x + 2x2)(x + -2)
Reorder the terms:
(1 + -3x + 2x2)(-2 + x)
Multiply (1 + -3x + 2x2) * (-2 + x)
(1(-2 + x) + -3x * (-2 + x) + 2x2 * (-2 + x))
((-2 * 1 + x * 1) + -3x * (-2 + x) + 2x2 * (-2 + x))
((-2 + 1x) + -3x * (-2 + x) + 2x2 * (-2 + x))
(-2 + 1x + (-2 * -3x + x * -3x) + 2x2 * (-2 + x))
(-2 + 1x + (6x + -3x2) + 2x2 * (-2 + x))
(-2 + 1x + 6x + -3x2 + (-2 * 2x2 + x * 2x2))
(-2 + 1x + 6x + -3x2 + (-4x2 + 2x3))
Combine like terms: 1x + 6x = 7x
(-2 + 7x + -3x2 + -4x2 + 2x3)
Combine like terms: -3x2 + -4x2 = -7x2
(-2 + 7x + -7x2 + 2x3)

Answer:
C. (-3, 6.5)
Step-by-step explanation:
Hope it helps.
I would say he has 3 $5 bills. He has a total of $25. Only $10 and $5 bills. If he has 1 $10 bill and 3 $5 bills, then that will total $25 and 3 times as many $10 the same as 3 x 1 = 3...so, 1 ($10) + 3 ($5) = $25
23.4 is the answer, hope this helps.:)
