Factorise
x^2+18x+80

Answers

Answer 1

Answer:

(x + 10)(x + 8)

Step-by-step explanation:

Given

x² + 18x + 80

Consider the factors of the constant term (+ 80) which sum to give the coefficient of the x- term (+ 18)

The factors are + 10 and + 8 , since

10 × 8 = + 80 and 10 + 8 = + 18 , then

x² + 18x + 80 = (x + 10)(x + 8) ← in factored form

In order to help her save money for college, Latasha's grandparents deposited $10,000 into a savings account five years ago. Latasha has not made any withdrawals or deposits since then. The interest rate on the savings account is 3.75% each year.
Using simple interest, how much interest has accrued in Latasha's savings account?

What is the total amount in Latasha's savings account?

Answers

Answer:

$11,875

Step-by-step explanation:

3.75×5 = 18.75%

[tex]\frac{18.75}{100}[/tex]×10000 = 18.75 × 100 = 1875 (we cut the zeros so that it will be easier to solve the equation)

10,000 + 1875 = $11,875 after 5 years

$1875 has accrued in Latasha's savings account

$11,875 is the total amount in Latasha's savings account after 5 years

alan , bispah and chan share a sum of money alan gets 1/8 of the money bispah gets 1/2 of the money chan gets the rest of the money alan gets 2.50 workout how much bispah gets

Answers

Answer:

bispha gets 10

Step-by-step explanation:

let total money be x

Alan gets 1/8 of x = x/8

bispha gets 1/2 of x =x/2

rest of the money = total -shared money

shared money = x/8 + x/2

[tex] = \frac{x + 4x}{8} = \frac{5x}{8} [/tex]

rest = x - 5x/8= 3x/8

Chan share = 3x/8

Alan = x/8

2.50 = x/8

x= 2.50×8= 20

total money is 20

bispha gets x/2 =20/2=10

what does x equal in this equation -5x + 8 = -2

Answers

Answer:

x = 2

Step-by-step explanation:

-5x + 8 = -2

-5x + 8 - 8 = -2 -8

-5x = -10

-5x/5 = -10/5

-x = -2

x=2

Simplify the equation:

-5x = 2 + 8

-5x = 10

x = -2

Write an equation of the line that passes through the given point and is parallel to the given line.
(4,7),y=5x-3
can you show how you solved it please ​

Answers

Step-by-step explanation:

y = 5x - 3 is in slope-intercept form.

The slope of this given line is 5,

=> Parallel line will also have slope 5.

We have y = 5x + c, where c is a constant.

When x = 4, y = 7.

=> (7) = 5(4) + c, c = -13.

Therefore the answer is y = 5x - 13.

Above lone woodland ways that led To dells the stealthy twilights tread The west was hot geranium red; And still, and still, Along old lanes the locusts sow With clustered pearls the Maytimes know, Deep in the crimson afterglow, We heard the homeward cattle low, And then the far-off, far-off woe Of "whippoorwill!" of "whippoorwill!"II. Beneath the idle beechen boughs We heard the far bells of the cows Come slowly jangling towards the house; And still, and still, Beyond the light that would not die Out of the scarlet-haunted sky; Beyond the evening-star's white eye Of glittering chalcedony, Drained out of dusk the plaintive cry Of "whippoorwill," of "whippoorwill."III.

Using the library and the Internet, find one research source about the topic. Your source should be at least five hundred words in length, or, if you select a print source, at least four to five pages.Choose one topic:a major Civil War battleCivil War munitions and uniformsthe Emancipation Proclamationthe Gettysburg AddressAfter you find your source, you should meet with your teacher to get it approved before moving on to the next step.Good readers rely on a set of skills to help them understand a text. You can use these strategies as you read the research source about the Civil War.If possible, print a version of the text that you can write on. It is helpful to highlight key points and make notes in the margins. This strategy is called annotating.When you find words or phrases that you do not know, do not skip over them. There is a series of steps you can take to understand the meaning of these words and phrases, so that you do not miss out on key ideas.Context clues: Look at the words before and after the unknown word or phrase. Using the surrounding text, or context, can you find any clues to the meaning of the unknown word?Using a dictionary: To find the specific meaning of a word, including helpful information like part of speech, word origin, and multiple meanings, you can use a dictionary. There are both print and online dictionaries available.Using an encyclopedia: Some words or phrases may have an important historical or contextual meaning behind them, especially in a social studies or history text. In this case, an encyclopedia is an excellent resource. For example, you would not want to simply use a dictionary to look up George Washington; in fact, an encyclopedia would provide you with a clearer meaning.After annotating the text, go back and read the text one more time. You might notice new details that you missed the first time.After you have finished reading the text a second time and have defined any unknown words, jot down some notes about the key points or ideas.
