Step-by-step explanation:
Sorry it took a bit not pretty good at these but i used an app called desmos and it basically gives the answer
Answer:the answer is the first
Step-by-step explanation:
Because the expression can be written as -10r2/2r2+4+5r/2r2+4+3/2r2+4
Answer:
Now, 3x 2+x+5⩾0
This is because b² −4ac=1−4×5×3
=−59 (roots are imaginary)
3x²+x+5=(x−3)² =x²+9−6x and x−3⩾0
2x²+7x−4=0
2x²+8x−x−4=0
2x(x+4)−1(x+4)=0
(2x−1)(x+4)=0
x= 1/2 and−4 but x≥3
∴ No solution.
lol hehehe
inches of snow is left
<em><u>Solution:</u></em>
Given that,
From given,
<em><u>how many inches of snow is left</u></em>
Snow left = original amount of snow - sun melted
