Question

.

Answer 1

\[(5x^2 + 3x + 4) − (2x^2 − 6x + 3)\]distribute the minus sign and get
\[5x^2 + 3x + 4 -2x^2 + 6x - 3)\]

Answer 2

since you are only asked for B you job is to compute \(3+6\)

Answer 3

yes

Answer 4

Add up 3x^2 - 9

and 2x + 9

So

(3x^2 - 9) + (2x + 9) = ???

Answer 5

5x^2 ?

Answer 6

Sorry, I didn't see the first x

Add x, 3x^2 - 9 and 2x+9

(x) + (3x^2 - 9) + (2x + 9)

x + 3x^2 - 9 + 2x + 9

3x^2 + 3x + 0

3x^2 + 3x

Answer 7

So after adding x, 3x^2 - 9 and 2x + 9, you will get 3x^2 + 3x, which is the total distance covered

Answer 8

soo its 3x^2 + 3x

Answer 9

add them up
\[x+3x^2 - 9+2x + 9\]

Answer 10

yes

Answer 11

thanks!

Answer 12

they really reach for these "word problems" don't they ?

Answer 13

they could have said "add the polynomials"

Answer 14

LOLLL yess they do !! Can you guys do me onee more favor and just double check my work ?

Answer 15

sure, what do you need to check

Answer 16

ill write the 5 questions and show you my answers

Answer 17

1. Simplify the following expression: (x − 8y) - (2x − 4y)If the final answer is written in the form Ax + By, what is the value of B?
2. Simplify: (4x − 6) − (5x + 1)
3. Simplify: (5x^2 + 3x + 4) + (5x^2 + 5x − 1)
4. Simplify: (4x − 6) + (3x + 6)
& You helped me with the other 2 questions so i just put the ones i did on my own but these were my answers
1. 4y
2. -x-7
3. 10x^2 + 8x + 5
4. 7x+12

Answer 18

ok one sec

Answer 19

alrighty :] Thanks!!

Answer 20

#1

the form is form Ax + By

they want the value of B, so the answer cannot be 4y

Answer 21

besides, -8y + 4y isn't 4y anyway

you lost a sign somewhere

Answer 22

Im bad with my signs /: negatives and positives -.- so confusing

Answer 23

think of it like this

-8 + 4

is the same as saying

you're 8 dollars in debt, but you paid off $4 of that debt, so you're now 4 dollars in debt

Answer 24

so that explains how -8 + 4 = -4

Answer 25

and why -8y + 4y = -4y

Answer 26

so itd be -4?

Answer 27

B is -4, yep

Answer 28

oki

Answer 29

# 2 is correct, so congrats on that

Answer 30

thanks :]

Answer 31

#3 is close

Answer 32

but not correct fully

Answer 33

4 + (-1) is NOT 5

Answer 34

-3?

Answer 35

you have 4 dollars

you add on 1 IOU

Answer 36

you really have 4-1 = 3 dollars left (after you pay off the IOU)

Answer 37

so that's why 4 + (-1) = 4 - 1 = 3

Answer 38

oh alright ! i get it now.

Answer 39

ok great

Answer 40

# 4 is also incorrect

Answer 41

sorry im blonde it takes a little bit.

Answer 42

that's ok, just practice practice practice

and hair color is just skin deep...has nothing to do with intelligence

Answer 43

Lol yeah , im guessing #4 is 7x-12

Answer 44

-6 + 6 = ???

Answer 45

-6 means you are $6 in debt

add on $6, so you are paying off $6

are you still in debt?

Answer 46

nope itd be zero :o

Answer 47

yep

Answer 48

-6+6 = 0

Answer 49

so the answers just 7x?

Answer 50

so you'd have 7x+0 or just 7x

Answer 51

you got it

Answer 52

ok aha :]

Answer 53

just watch out for the signs and try not to forget any

Answer 54

Ill think of the whole dollar thing next time i come to the signs , Thank you so much ! ! :]

Answer 55

that's how I grasp negatives when I stumble a bit, and you're welcome

Answer 56

Ive always troubled negatives , ive been taking algebra 1 for 3 years now , and havent passed . Im working so much harder now ,

Answer 57

have you thought of using money terms for negatives before? I'm just curious how your teachers have taught negatives in the past

Answer 58

ive heard of it but it was never enforced.

Answer 59

I gotcha, so they brought it up (maybe once or twice), but never really stuck to it

Answer 60

nopeeeee

Answer 61

Im trying to finish up my work for next week so im ahead so i can spend my spring break with my younger sister , would you mind helping me with Multiplying monomials?

Answer 62

sure I can help

Answer 63

Choose the correct simplification of the expression d^3 • d^5.

d

d^15

d^2

d^8

Answer 64

what did you get

Answer 65

the arrow represents the degree of the monomials incase you didnt already know lol.
and i think its d^15??

Answer 66

^ means exponents, yes I know

and no it's not d^15

Answer 67

if you are multiplying expressions with the same base, then you add the corresponding exponents

Answer 68

example

x^2 times x^3 = x^(2+3) = x^5

Answer 69

Alright that sounds a little better so d^8 ?

Answer 70

because you can expand out the 'x' terms and you'll see 5 total x terms

Answer 71

yep d^8

Answer 72

alright you make this so much easier than the lesson lol

Answer 73

lol glad to hear that

Answer 74

glad it's finally clicking

Answer 75

Choose the correct simplification of the expression (b^5)^4.

b^9

b^625

b^20

b

Answer 76

b^20 ?

Answer 77

you got ???

Answer 78

perfect

Answer 79

you're a total pro at this

Answer 80

HA i wish!

Answer 81

you're just not giving yourself enough credit

Answer 82

Choose the correct simplification of the expression (3x)^4.

81x^4

12x^5

81x^5

12x^4

Answer 83

raise each piece to the 4th power

Answer 84

81x^4 ?

Answer 85

so you raise 3 to the 4th power to get ____

Answer 86

yep, you got it

Answer 87

see you know this stuff

Answer 88

haha slowly but getting it !! :)

Answer 89

well as long as you get there, that's all that matters

Answer 90

Choose the correct simplification of the expression (x^2y)^2.

x^4y^3

x^6y^6

x^4y^2

xy^4

Answer 91

what did you get

Answer 92

Havent even tried it yet lol .but im thinking the ^2 on the outside is going to distribute to the ones in the parenthese?

Answer 93

yes that's one way of thinking about it

basically you raise each part to the 2nd power

Answer 94

x^2 to the 2nd power ----> x^2 * x^2 = x^(2+2) = x^4

Answer 95

y to the second power -----> y^2

Answer 96

or you can multiply the exponents

multiply the outer by each of the inner

Answer 97

so x^4y^2

Answer 98

yep
