Answer:
cos
Step-by-step explanation:
take 31 degree as reference angle
using cos rule
cos 31=adjacent/hypotenuse
0.85=14/x
x=14/0.85
x=16.47
x=16.5

If the perimeter of a parallelogram is 50cm and one side is12
cm. what is the measure of the other side ?
Area = 100Sq/in
Perimeter = 40
Easiest side length would be 10in x 10in = 100sq/in (ie a square)
Instead of a square, the 100sq in could be 100 laid out in a long row: the perimeter therefore would be 100 + 1 + 100 + 1 = 202in. Not a square
Answer:
f(x) = 3x² + 6x + 3
Step-by-step explanation:
The standard form of a quadratic is 
. To write the equation f(x)=-3(x+1)(x+1) in standard form, multiply the factors using the distributive property and combining like terms.
f(x)=-3(x+1)(x+1)
f(x) = 3(x²+x+x+1)
f(x) = 3x² + 3x + 3x + 3
f(x) = 3x² + 6x + 3
