$9
Step-by-step explanation:
Answer:
Move everything so all terms are on one side of the = sign, and solve for zero using the Quadratic Formula. There are two answers: v=7±√69
10
Step-by-step explanation:
Subtract 1 from both sides so you have
e "standard form" of a quadratic is
, so first we have to identify a, b, and c in your equation: a=5, b= -7, and c= -1.
The quadratic formula is
. Plugging in your values, we get
−
. It looks a little funny, but you can't simplify it any more. You can check the answer by graphing the function on your calculator and asking for the function value at these points.
After graphing, hit 2nd, "Calc", "Value" on your TI, and type in either
, and you'll get that
X-4y=7 Answer:1/4
2x+y=5
2x+y=5 I am not sure but I’m pretty sure the answer is -2
18,000 should be the answer
Answer:
Blue = 116 m^2
Step-by-step explanation:
The area of the path and the square = 30*30 = 900 m^2
The size of the square = 30 - 2 = 28. The square = 28^2 = 784
The path takes up the difference between the two 900 - 784 = 116
