If k-5=10b what is b when k=-90

Step-by-step explanation:

k-5=10b

-90-5=10b

-95=10b

b=-9.5

b= -19/2 or simplified would be b= -9.5

Step-by-step explanation:

Your problem says k-5=10b

I put (-90)-5=10b in my calculator.

Then I checked my answer and got the equation would be true on both sides.

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1
