AB = sqrt(10^2 - 4^2) = sqrt(100 - 16) = sqrt(84) = sqrt(4 x 21) = 2sqrt(21) = 2 radical 21.
Answer:
3-3 -4-3=0
Step-by-step explanation:
just divide 3-3 and -4-1 and u get your answer
You need to add the two quadratics together...
x^2+11x-6+6x^2-3x+9
7x^2+8x+3

Multiply the top equation by -3 and added to the second one.
By Elimination.
