Write a polynomial expression for the perimeter of a triangle whose sides have the following lengths. X + 8, 3x^2+4x, x^2 - 3x +6 A. 4x² + 5x+6
B. 3x²+2x+2
C. 4x²+2x+14
D. 3x²+8x+8​

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

according to egenuity the answer is

step-by-step explanation:

d. 344.22

choice b

step-by-step explanation:

f(x) = 88x^2 -264x + 300

the line of symmetry of a parabola is defined by

h = -b/2a

where ax^2 +bx+c=0

so

h = - -264/ (2*88)

h = 3/2

so x = 1.5
