The expression x^4-16 is equivalent to the product of (x+2) and p(x) which expression could represent p(x)
bagirrra123 [75]
Easy
differnce of 2 perfect squares
a²-b²=(a+b)(a-b)

in this case
x⁴=(x²)²
16=4²

(x²)²-4²=(x²+4)(x²-4)
x²-4 can be factored since 4=2²
x²-2²=(x+2)(x-2)

complete factored form is
(x²+4)(x+2)(x-2)
gegroup to seperate (x+2)
(x+2)[(x²+4)(x-2)]
(x+2)p(x)

p(x)=(x²+4)(x-2)
expanded
p(x)=x³-2x²+4x-8

Write the equation of the line that passes through the points (-1, 10) and (5, 2)
sdas [7]

Answer:

y=-\frac{4}{3}x +\frac{26}{3}

Step-by-step explanation:

1) if the point A has coordinates (-1;10) and the point B - (5;2), then it is possible to write common view of the required equation of the line:

\frac{x-X_A}{X_B-X_A} =\frac{y-Y_A}{Y_B-Y_A};

2) if to substitute the coordinates of A&B into the common equation, then:

\frac{x+1}{5+1} =\frac{y-10}{2-10}; \ => \frac{x+1}{6}=\frac{y-10}{-8};

3) finally, in slope-intersection form:

3y= -4x+26; ⇔ y= -4/3 x +26/3.

P.S. the suggested way of the solution is not the only one.

What is the greatest common factor of x4 and x3
Dvinal [7]

Answer:

x3

Step-by-step explanation:

Considering x4 and x3 actually power terms.

I mean: x4 is x^{4} and x3 is x^{3}.

Let's decompose the first term: x^{4}=x^{3}.x

Now it is clear that the common factor is x^{3}.

Amount of almonds = 18 × [2/9]

Amount of almonds =  4 almonds

Step-by-step explanation:

Given:

Number of mixed nuts = 18

Probability of almonds = 2/9

Find:

Amount of almonds

Computation:

Amount of almonds = Number of mixed nuts × Probability of almonds

Amount of almonds = 18 × [2/9]

Amount of almonds = 36 / 4

Amount of almonds =  4 almonds
