Answer:
The first one.
Step-by-step explanation:
A solid figure is a closed shape. If you do mental calculation, the first one is the only one that is solid, or closed.
still, if you have any doubt ask me!
Formula is Ya-Yb/Xa-Xb
The slope is 13/2 but in decimal form it’s 6.5.
Discriminant D is given by:
D=b²-4ac
Implication of discriminant is as follows:
D<0 two zeros that are complex conjugate
D=0 one real zero of multiplicity 2
D>0 two distinct real zers
D= (+ve perfet square) two distinct rational zeros
From:
12x^2+10x+5=0
plugging in the equation we get:
10²-4×12×5
=100-240
=-140
thus
D<0
