Answer:
Standard form of a quadratic equation is;
ax^2+bx+c=0
According to the above equations, all of them are in standard form.
Step-by-step explanation:
Answer:3x^2+2x+10=0
its for sure C
<em>122.46 cm² </em>
A =
~~~~~~~~~
= 8 cm
= 5 cm
A = 3.14 ( 8² - 5² ) ≈ <em>122.46 cm²</em>
The width of pen A is 7 feet,
The Length of Pen A is 11 feet,
The width of Pen B is 6 feet,
The Length of Pen B is 12 feet
The Length of Pen A is 7 + 4 = 11 feet,
The width of Pen B is 7+4-5 = 6 feet,
The Length of Pen B is 2*(7+4-5) = 12 feet
