Answer:

1) Answer: 3)  ~~x = -3 \pm \sqrt{7}

2) Answer: 3) 2 and -6

Step-by-step explanation:

1)

(x + 3)^2 = 7

x + 3 = \pm \sqrt{7}

x = -3 \pm \sqrt{7}

Answer: 3)~~x = -3 \pm \sqrt{7}

2)

2(x + 2)^2 - 4 = 28

2(x + 2)^2 = 32

(x + 2)^2 = 16

x + 2 = \pm \sqrt{16}

x + 2 = \pm 4

x + 2 = 4   or   x + 2 = -4

x = 2   or   x = -6

Answer: x = 2 or x = -6

Hank's pickup can travel 72 miles on 4 gallons of gas. How many gallons will Hank's pickup need to travel 54 miles?
Ira Lisetskai [31]

Answer:

3 gallons of gas

Step-by-step explanation:

First we need to create the ratio to build our answer off of.

This ratio would be 72:4, meaning 72 miles for every 4 gallons.

We can divide 72 by 4 to find the unit rate.

72 / 4 = 18

So, the unit rate is 18 miles for every 1 gallon.

Next we need to figure out how may gallons are needed to travel 54 miles.

We can divide 54 by 18 to receive 3.

This means that our ratio needed to answer the question is 3 times the unit rate.

Our new ratio is now: 54:m, m meaning miles.

To find the amount of miles, multiply the 3 we used later, to make this ratio 3 times the unit rate.

So, our final ratio is 54:3,

meaning that Hank will have used 3 gallons of gas after traveling 54 miles.
