Answer: D, When the constants are perfect squares.
Step-by-step explanation:
the “best” method whenever the quadratic equation only contains x2 terms. That implies no presence of any x term being raised to the first power somewhere in the equation.
Hopefully this helps!
Answer:
Step-by-step explanation:
r=4*l
t=r-8
t=4l-8
r+t+l=100
4l+4l-8+l=100
9l-8=100
+8 +8
9l=108

l=12 Layla score
4*12=48 Rani score
48-8=40 Tash score
verify 12+40+48=100 correct
You multiply the denominator on one side of the equation by the numerator and vice versa. So for example(S)I'm going to multiply 4 by nine and 3 times n. Then that comes out to 3n=36. After you multiply, you divide from both sides to get the variable by itself. So you would divide both sides by 3 and you're final answer would be n=13. Hope this helped!

Answer:1
Step-by-step explanation: substitute all the corresponding terms so you get, 16=4(3+b2)
Then you multiply and get 16=12+4b2 then subtract 12 from both sides to get 4=4b2 and then divided both sides by 4 and you get 1=b2
