Answer:

some do not have numbers so I tried to make the linking as easy to understand as possible, with answers in bold.

Step-by-step explanation:

(6x + 6) + (-3 - 4x) = 2x + 3

4) = 12x - 2

(6p + 4) + (-5p + 8) = p + 12

6) = -n + 5

(-8r + 8) + (-7 - 7r) = -15r + 1

8) = 6r - 13

(1 - 6x) + (7x + 3) = x + 4

10) = -12x - 3

a^4+b^4=(a^2)^2+(b^2)^2

=(a^2+b^2)^2–2a^2b^2

=(a^2+b^2)^2—(√ 2ab)^2

=(a^2+√ 2ab+b^2)(a^2-√ 2ab+b^2)

jeka94

Answer:

t = 5 seconds

Step-by-step explanation:

A golfer takes a swing from a hill twenty feet above the cup with an initial upwards velocity of 76 feet per second.

We need to find how long does it take the ball to land on the ground near the cup.

The equation for the path of the ball is given using second equation of kinematics as follows :

$-16t^2+76 t+20=0\\\\\text{or}\\\\-4t^2+19t+5=0\\\\-4t^2+20t-t+5=\\\\-4t(t-5)-1(t-5)=0\\\\(t-5)(-4t-1)=0\\\\t=5, t=\dfrac{-1}{4}\ s$

Neglecting negative value,

It will take 5 seconds for the ball to land on the ground near the cup.

Andreas93 [3]

Answer:

There are 800 total books.

Step-by-step explanation:

In order to find this, we need to create a proportion that compares the number of non-fiction books to the total. First would be the scale factor and the second would be the total.

3/10 = 240/x

Now we can cross multiply to solve

240*10 = 3 * x

2400 = 3x

800 = x
