Question

Use the distributive property to simplify the expression below:
−2(d − 4) + 3d

Answer 1

\(\Large \color{MidnightBlue}{\Rightarrow -2d + 8 + 3d }\)

\(\Large \color{MidnightBlue}{\Rightarrow d + 8 }\)

Answer 2

Evaluate: 14 − 10 ÷ 2 + 3

Answer 3

Use BODMAS in this one.


\(\Large \color{MidnightBlue}{\Rightarrow 14 - (10 \div 2) + 3 }\)
\(\Large \color{MidnightBlue}{\Rightarrow 14 - 2 + 3 }\)
\(\Large \color{MidnightBlue}{\Rightarrow 14 + 1 }\)
\(\Large \color{MidnightBlue}{\Rightarrow 15 }\)

ok im gonna try to do this math problem
Simplify the following expression.
2x − 2y + 3z − 2x − y + 2z = ?

Answer 18

3y+5z?

Answer 19

Nope

Answer 20

-3y?

Answer 21

2x − 2y + 3z − 2x − y + 2z.. Lets rearrange the like terms as
(2x− 2x)+(3z+2z)+(-2y-y) and now do the calculation
(0)+(5z)+(-3y) = 5z-3y Got it ?

Answer 22

Yes =)

Answer 23

im pretty sure i got it

Answer 24

thanks for your help

Answer 25

mind giving me a problem so i can solve?

Answer 26

Answer 29

or 42xy-11?

Answer 30

did i do it correcT?

Answer 31

No!

Answer 32

what did i do wrong?

Answer 33

the terms which are of same form..bring them together and bracket them as i did...in ur problem 15x2y+9xy+4−9x2y−3xy−15 = (15x2y-9x2y)+(9xy-3xy)+(4-15)= 6x2y+6xy-11 got it this time ?

Answer 34

Bryan..u ok ?

Answer 35

yeah

Answer 36

just learning

Answer 37

oh so i basically could of gotten it correct if i hadent solved the 6 to the power

vikash you ok?

Answer 40

The problem is that you are not confident of your method..you are coming up with multiple answers for the same question. You need to understand the mechanism well and apply it uniformly in all other problems.. Let me tell you..whenever you solve some new type of problem..do not rush to the new one immediately. Hold on..have a look at the problem you just solved..understand the concept..see how it applies and only then move to the next problem. If you follow this you will never repeat your mistakes.

Answer 41

do not rush to the next problem immediately. *

Answer 42

ok i will trry not to
