Answer:
b and c
Step-by-step explanation:
Answer:
a = 21
Step-by-step explanation:
If x = h is a zero of a polynomial then f(h) = 0, thus
p(-
) = 27( -
)³ - a(-
) - (-
) + 3 = 0, that is
27 (-
) -
a +
+ 3 = 0
- 1 -
a +
= 0 ( multiply through by 9 to clear the fractions )
- 9 - a + 30 = 0
- a + 21 = 0 ( subtract 21 from both sides )
- a = - 21 ( multiply both sides by - 1 )
a = 21
Aye the Answer is D ~hope that helps :)
He needs 1/2 cup because 3/4-1/4=2/4 which is simplified to 1/2
5z>15-----subtract 2 on both sides
z>3----divide by 5
therefore, z must equal -10, or -4
