The Johnson twins were born four years after their older sister. This year, the product of the three siblings ages is exactly 34
svp [43]

Answer:

Step-by-step explanation:

Let age of each twin be x

let age of sister be s

So we can write:

x + 4 = s

The product of the 3 siblings ages is 3482 more than sum. We can write:

s*x*x=3482+(s+x+x)

This can be simplified as:

sx^2=3482+s+2x

We replace s with "x + 4" and solve:

(x+4)x^2=3482+x+4+2x\\x^3+4x^2=3486+3x\\x^3+4x^2-3x-3486=0\\x=14

<u>Note:</u> To solve this cubic, we used technology

Thus, we can say the twins are 14 years old

Answer:

acceleration of the golf ball will be faster. (  A  )

Step-by-step explanation:

if you DROP a bowling ball vs a golf ball, the bowling ball will drop faster cause it’s heavier. but if you push a golf ball vs a bowling ball with the same force, the golf ball will be faster because it’s lighter. pushing a bowling ball with a lot of force will move it a certain amount, but moving a golf ball with that same force will go way past the bowling ball just cause it’s lighter.

Consider the polynomial below.
kotykmax [81]

Answer:

(-4x - 2)(-5x) + (-4x - 2)(3)  

Step-by-step explanation:

Your polynomial is

(-4x - 2)(-5x + 3)

The distributive property states that

a(b + c) = ab + ac

Let a = -4x - 2.  Then

(-4x - 2)(-5x + 3) = a(5x + 3) = a(-5x) + a(3)

Substitute the value of a.

a(-5x) + a(3) = (-4x - 2)(-5x) + (-4x - 2)(3)

You have just distributed the first binomial (-4x - 2) among the terms of the second binomial.
