Answer:

RT=75/4= 18.75

Step-by-step explanation:

RS+ST=RT

x+6+8=5x-5

4x=19

x=19/4

RT=5x-5

RT=5(19/4)-5

RT=95/4-20/4

RT=75/4= 18.75

Answer:

$7x^{2}-2x-12=0$

Step-by-step explanation:

we know that

The standard form of the quadratic equation is equal to $ax^{2} +bx+c=0$

we have

$(5x^{2}-3x-2)-(-2x^{2}-x+10)$

eliminate the parenthesis

$5x^{2}-3x-2+2x^{2}+x-10$

group terms that contain the same variable

$(5x^{2}+2x^{2})+(-3x+x)+(-2-10)$

combine like terms

$7x^{2}-2x-12=0$

AB/AC = 7/13

Take AB as x aight

x/x+18 = 7/13
