Answer:
Step-by-step explanation:
3x^2 = 24
devide by 3
x^2 = 8
x =2.828427125
Answer:
8
Step-by-step explanation:
well because since you have to add u add 3+b
you substitute 5y+41 for x and get 5y+41+3y=-15 then you simplify by doing 8y+41=-51 subtract 41 from each side and divide by 8 to get y alone. That's how you get 11.5 for your answer.
