Answer:

if u answer my question i will answer yours

Step-by-step explanation:

2x^2  - 5x  +  k  =   0

 

If  this has one solution then the discriminant  = 0

 

So

 

(-5)^2  - 4 (2) k   = 0

 

25  - 8k  = 0

 

25  =  8k

 

25/8  = k

Help with this please. I’d appreciate if you showed the steps and the answer. Thanks!
olga55 [171]
17^2 because the equation for it is a^2+b^2=c^2 so the longest side (x) is the c so 10 i put as a and 7 i put as b. it will always be squared for pythagorean theorem so the equation will look like 10^2+7^2=17^2 and if it isn’t squared all you have to do is undo the squaring
