Find the difference in gallons and the difference in the weights

46 - 12 = 34 gallons

2399 - 2176 = 223 pounds
so 34 gallons of gas weighs 223 pounds

find weight per pound: 223 pounds / 34 gallons = 6.5588 pounds per gallon
round to 6.6 pounds per gallon

54 gallons - 46 gallons = 8 gallons

8 gallons x 6.6 pounds per gallon = 52.8 pounds, round to 53 pounds

2399 + 53 = 2452 weight of plane with 54 gallons

Answer:

Step-by-step explanation:

larger rectangle:

22 x 12 = 264

to find unlabeled rectangle:

18 - 12 = 6

22 - 15 = 7

6 x 7 = 42

total area:

264 + 42 = 306

306/16.25 = 18.83

you can't buy 18.83 cases, so you round up and buy 19

Which function is a quadratic function? a(x) = –2x^3 + 2x – 6 b(x) = 5x^3 + 8x^2 + 3 c(x) = –8x^2 + 3x – 5 d(x) = 6x^4 + 2x – 3

Sedaia [141]

Answer:

c(x) = –8x^2 + 3x – 5 is a quadratic

Step-by-step explanation:

A quadratic function involves the 2nd power of x: x^2, and may (or may not) involve the 1st and zeroth power of x.

a(x) = -2x^3 is not a quadratic because of that exponent 3; in a quadratic, the highest power is always 2.

b(x) = 5x^3 + 8x^2 + 3 is not a quadratic for the same reason that a(x) is not a quadratic.

c(x) = –8x^2 + 3x – 5 is a quadratic: the highest power of x is x^2, the other powers are x^1 and x^0.

<h2>Hello!</h2>

The answers are:

3. Addition property of equality

4. $6x-7+7=12+7$ - Simplification

7. $x=\frac{19}{6}$

To solve the problem, we need to start with the result of the second step:

$6x-7=12$

So,

For the step 3:

Then, for the 3rd step, we have to apply the addition property of equality.

The addition property of equality states that if we add a term to one side of the equality, we need to add it to the other side of the equality, in order to not alterate the equality.

Then, applying the property, we have:

$6x-7=12$

Adding 7 to both sides, we have:

$6x-7+7=12+7$

For the step 4:

Now, for the 4th step, we have to simplify the expression:

$6x-7+7=12+7$

Then, simplifying, we have:

$6x=19$

For the step 7:

Simplificating, we divide each side of the equality by 6:

$\frac{6x}{6}=\frac{19}{6} \\\\x=\frac{19}{6}$

Have a nice day!
