We have that
x²<span>-2x-(2p+3)

if </span><span>-4 is a zero of the polynomial
so
for x=-4
</span>x²-2x-(2p+3)=0----> (-4)²-2*(-4)-(2p+3)=0-----> 16+8-2p-3=0
21-2p=0
2p=21
p=21/2-----> p=10.5

Answer:

b ≈ 4.2

Step-by-step explanation:

Using the tangent ratio in the right triangle, that is

tan50° = \frac{opposite}{adjacent} = \frac{BC}{AC} = \frac{5}{b} ( multiply both sides by b )

b × tan50° = 5 ( divide both sides by tan50° )

b = \frac{5}{tan50} ≈ 4.2 ( to the nearest tenth )

I know the answer is C. but I need to know how to solve it!
otez555 [7]
Yes you are right it's C)
Notice  that f(-2) = (-2)³ +2( - 2)² + 4(-2) + 8 =0
Then x³+2x²+4x+8 is divisible by (x+2)
Perform this division & you will get:

x³+2x²+4x+8 = (x+2)(x²+4)
 The root of (x+2) is the value that render it nil, that is x=-2
  The root of (x²+4) are imaginary (not real) because
  x²+4 =0 ==> x² = -4 & x=√-4 or x= 2i (nor real).
Hope you understood the reasoning

I’ve broken it down into the parts that you’ve highlighted:

Part A:
x = 25 + y
x + y = 95

Part B:
I’m using the substitution method to find the amount of time that Eric plays volleyball, so:
x + y = 95
x = 95 - y
95 - y = 25 + y
70 = 2y
y = 35, 35 minutes spent playing volleyball

Part C: i don’t completely understand the question, perhaps there was a typo?
