PLEASE HELP ASAP
maria [59]

Answer:

First option:  3x^2-5x=-8

Second option: 2x^2=6x-5

Fourth option: -x^2-10x=34

Step-by-step explanation:

Rewrite each equation in the form ax^2+bx+c=0 and then use the Discriminant formula for each equation. This is:

D=b^2-4ac

1) For 3x^2-5x=-8:

 3x^2-5x+8=0

Then:

D=(-5)^2-4(3)(8)=-71

Since D this equation has no real solutions, but has two complex solutions.

2) For 2x^2=6x-5:

 2x^2-6x+5=0

Then:

D=(-6)^2-4(2)(5)=-4

Since D this equation has no real solutions, but has two complex solutions.

3) For 12x=9x^2+4:

 9x^2-12x+4=0

Then:

D=(-12)^2-4(9)(4)=0

Since D=0 this equation has one real solution.

4) For -x^2-10x=34:

 -x^2-10x-34=0

Then:

D=(-10)^2-4(-1)(-34)=-36

Since D, this equation has no real solutions, but has two complex solutions.

Please help me with 1,2,3,show me how you get the answers and show me the steps for 1,2,3,please do not send me link write it ri
Natali [406]

Answer:

Step-by-step explanation:

1. ok so you need to use Pythagoras which is a^2 + b^2 = c^2

substituting 16 and 12 into 'a' and 'b' you get 16^2 + 12^2 = c^2

256 + 144 = c^2

400 = c^2 (square root each side to get ride of the square)

c = 20cm

2. doing the same thing you get c = 22.36 in

3. again doing it you get c = 15Ft

 Hope this helps!
