X2 + 2x + 10 =0
Can also be written as 2x +2x + 10 =0
4x + 10 =0

Product of 21.33 and 2.04 and the sum of 1.115, 3.18, 22.0613and 12.2384

larisa [96]

Step-by-step explanation:

A. Line up the decimals, then multiply as you would with whole numbers:

$21.33 \\\times 2.04 \\ = 43.5132$

B. Line up the decimals, then add as you would with whole numbers:

Note: These decimals aren't lined up exactly.

$1.115 \\ + 3.18 \\ = 4.295$

$22.061 \\ + 4.295 \\ = 26.356$

$26.356 \\ + 12.2384 \\ = 38.5944$

Pllllllease help me asap

Answer & Step-by-step explanation:

When we see the phrase "rate of change" then it means that we are looking for the slope. So, we will need to know the formula for finding slope or the rate of change.

$slope=\frac{y_2-y_1}{x_2-x_1}$

Now, let's use this equation to solve for the rate of change of each question.

Problem 1:

$Slope=\frac{2-\frac{4}{3}}{0-(-1)}\\\\Slope=\frac{\frac{2}{3}}{1}\\\\Slope=\frac{2}{3}$

The rate of change of this equation is 2/3

Problem 2:

$Slope=\frac{4-2}{1-0}\\\\Slope=\frac{2}{1}\\\\Slope=2$

The rate of change for this equation is 2

Problem 3:

$Slope=\frac{10-4}{2-1}\\\\Slope=\frac{6}{1}\\\\Slope=6$

The rate of change for this equation is 6

Sylvia has a piece of material that is 668.36 square inches. She marked the material into 4 equal pieces and then cut out one of

sveta [45]

The whole magic jug had 668.36 ounces of mysterious elixir in it.
Sylvia came along and marked it into 4 equal amounts, so each
amount was (1/4) of (668.36 ounces).

Now, you would have us believe, she tucked the magic jug under her cloak,
walked quickly and quietly down the hall into the shadows, pulled the jug out,
and quaffed one of the equal amounts from it, all in one slug.

The quantity remaining in the jug was then

(3/4) of (668.36 ounces) = 501.27 ounces.

The same process works for length, volume, area, stones, money, anything.
If you divide up what you have into 4 equal parts, then each part is 1/4 .
If you eat, sell, lose, or give away 1/4 of it, you have 3/4 left.
