What is y = –3(x – 3)(x + 7) in standard form ?

−3x^2-12x+63

Step-by-step explanation:

simplify-3(x-3) you should get -3x+9.

then use foil to get (-3x+9)(x+7)

you multiply -3x with (x+7) and tou should get (-3x^2-21x)

then multiply 9 with (x+7) and you should get (9x+63)

now you should have the numbers: -3x^2, -21x, 9x, and 63.

combine like terms: add 9x to -21x and tou will get -12x.

Now place the numbers in the correct order: variables with exponents, then nirmal variables, then non variables

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
