Wayne is putting tools into a toolbox, one at a time. He wants to include a pair of pliers, a
vise grip, a roll of duct tape, and a putty knife. In how many different orders could he add
these tools?

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

is the anwser b. (-13)?

josh is incorrect

x= 7 and x= -1

step 2 is wrong and honestly first step is not needed, you just need to figure out the factors

i know its wrong because if you plug in the solutions josh found, they do not work (in the original equation)

x^2 -6x -7 = 0

(x-7) (x+1) = 0

x-7=0 x+1=0

x= 7 x= -1
