Find the value of k that would make the left side of the eequatios a perfect square trinomial. value of k that would make the left side of the equation a perfect square trinomial.

64x^2-kx+1=0

x^2-kx+16=0

4x^2-kx+9=0

16x^2+kx+9=0

(1/4)x^2-kx+(1/25)=0

the numbers in parenthesis are fractions!!

$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
