The only number that fits is 41. 1 is 3 less than 4 and 41 is prime.
Answer:
C. 40 cm
Step-by-step explanation:
length of side of square = s
perimeter = s + s + s + s = 4s
We use the formula P = 4s
P = 4 * 10 cm
P = 40 cm
Answer: The perimeter is 40 cm.
Notice that the perimeter is a sum of lengths, so its units are linear units such as cm, inches, feet, a unit of length.
An area has square units such as cm^2, in.^2, ft^2, etc.
The answer would be 361/4 added to each side of the formula
Answer:
I will assume the equation is supposed to be f(x) = <u>x^2</u> – 5x + 12 since it is said to be a quadratic equation.
Step-by-step explanation:
<u>See attached graph.</u>
The value of f(–10) = 82 <u><em>False</em></u>
f(-10) = (-10)^2 - 5*(-10) + 12
f(-10) = (100) +50 + 12
f(-10) = 162
The graph of the function is a parabola. <u><em>True</em></u>
The graph of the function opens down. <u><em>False</em></u>
The graph contains the point (20, –8). <u><em>False</em></u>
The graph contains the point (0, 0). <u><em>False</em></u>
Answer:
Step-by-step explanation:
a+pR^2-2pr^2, since R=15 and r=7.5
A=225p-112.5p
A=112.5p
a= 353.25ft^2
