(5x-4y)^2
(5x-4y)(5x-4y)

Multiply each term in one bracket in turn by the terms in the other bracket

(5x)(5x) = 25x^2
(5x)(-4y)=-20xy
(-4y)(5x)=-20xy
(-4y)(-4y)=16y^2

Put them together we have
25x^2-20xy-20xy-16y^2
25x^2-40xy-16y^2

How can i solve for y in this problem? 2x-y=3
pshichka [43]

Hello from MrBillDoesMath!

Answer:

y = 2x - 3

Discussion:

2x - y = 3  =>                  add "y" to both sides

2x - y + y = 3 + y =>        as -y+y = 0

2x = 3 + y    =>                subtract 3 from each side of the equation      

2x-3 = y


Thank you,

MrB

How do i write 12.009 in a word form?
tia_tia [17]
Your answer will be twelve and nine thousandths because in place value decimals are like tenths, hundredths, thousandths. In place value for regular numbers are ones, tens, hundreds and so on. So, when you have 12.009, you are going to separate the decimals with the numbers. Then, write down the number in words which would be twelve. Now, go to the decimal and write that down, which is 9 thousandths. Finally, combine the both of them to get: twelve and nine thousandths.

Hope this helps :) 
and good luck

See the attached picture for 2 options for question 1 and 2 depending on how the fractions are written.


Question #3:

17 = -13 - 8x

Add 13 to each side:

30 = -8x

Divide both sides by -8:

X = 30 / -8

X = -3 3/4
