Answer: −y^2+18y

Let's simplify step-by-step.

5y(4−(y+2))+4y(y+2)

Distribute:

=(5y)(4)+(5y)(−y)+(5y)(−2)+(4y)(y)+(4y)(2)

=20y+−5y2+−10y+4y2+8y

Combine Like Terms:

=20y+−5y2+−10y+4y2+8y

=(−5y2+4y2)+(20y+−10y+8y)

=−y^2+18y

Answer:

= −y^2+18y

Answer:

7^3 + 7^3 units^3

OR

(7^3)2 units^3

Step-by-step explanation:

Volume = length x width x height

In cubes, length = width = height

So, volume = 7 x 7 x 7 = 7^3

2 cubes:

7^3 + 7^3 units^3

OR

Step-by-step explanation:

Answer:

Step-by-step explanation:

Complementary angles are two angles that add up to be 90 degrees.

We can write an equation and solve for x.

(3x - 4) + (5x + 6) = 90

~Combine like terms

8x + 2 = 90

~Subtract 2 to both sides

8x = 88

~Divide 8 to both sides

x = 11

Angle DEF:

3x − 4

3(11) - 4

33 - 4

29°

Angle FEG:

5x + 6

5(11) + 6

55 + 6

61°

Check:

29 + 61 = 90°

Best of Luck!

Answer:

Step-by-step explanation:

Where are the answer choices?

Still, it's possible to help you without your having shared those choices.

The "difference quotient" is defined as:

 f(x + h) - f(x)

--------------------

           h

where h represents an incremental (small) change in x.

Here f(x) = 3 - log x, and so f(x + h) = 3 - log (x + h).

Therefore the difference quotient is:

{3 - log (x + h)} - {3 - log x}

-------------------------------------

                    h

This can be simplified.  In the numerator we have 3 - 3, so the numerator simplifies to -log (x + h) + log x

and the difference quotient is

-log ( x + h) + log x

---------------------------

              h

This can be rewritten as

log x - log (x + h)                                x                                  x

--------------------------- , or (1/h)*log ------------ , or  (1/h) log { ----------- }

              h                                       (x + h)                            x + h

Answer:

[tex]x=-8[/tex]

Step-by-step explanation:

[tex]\frac{x}2} -x=\frac{x}{4} +6[/tex]

Let's begin by getting rid of the fractions by multiplying both sides of the equation by the least common multiple of the denominators 2 & 4 (4).

[tex]4(\frac{x}2} -x)=4(\frac{x}{4} +6)[/tex]

Distribute:

[tex]\frac{4x}{2} -4x=\frac{4x}{4} +24[/tex]

Simplify:

[tex]2x-4x=x+24[/tex]

Combine like terms:

[tex]-2x=x+24[/tex]

Subtract [tex]x[/tex] from both sides of the equation:

[tex]-3x=24[/tex]

Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]-3[/tex]:

[tex]x=-\frac{24}{3}[/tex]

Simplify:

[tex]x=-8[/tex]

Answer:

0.4

Step-by-step explanation:

Answer:

0.4

Step-by-step explanation:

The tenths has 3, the hundredths has 6, and the thousandths has 2. The hundredth is greater than 5, so we have to round the tenths up by 1, making it 0.4

Answer: 24100

Step-by-step explanation:

The money in the account after 8 years is $24068.631.

Given that, principal=$19000 and the rate of interest=3%.

The formula to find the compound interest is CI=A-P.

Where, A=Amount that is [tex]A=P(1+\frac{r}{100} )^{n}[/tex], P=principal.

Now, [tex]A=19000(1+\frac{3}{100} )^{8}[/tex]

=19000[tex](1.03)^{8}[/tex]

=19000×1.26677008139

=$24068.6315464

=$24068.631

Therefore, the money in account is $24068.631.

Hope This Helps :)

The required rate for granola in dollars per pound is 1.25.

In order to solve a problem for two different values of a quantity, its unit value is first derived. This method is known as unitary method.

Given that,

The total money spent on granola is $3.75.

And, the amount of granola is 3 pounds.

The unit rate for the given case can be found using unitary method as,

Money spent for 3 pounds = $3.75

Then, money spent for 1 pound = 3.75/3 = $1.25

Hence, the rate of granola $1.25 per pound.
