Answer:
4
Step-by-step explanation:
3y - 4 + 2y
0 = 3y - 4 + 2y
4 + 0 = 3y - 2y
4 = y
y = 4
is this what you want ?
Assume you mean 3x^2 when you typed the question.
3x^2+14x+16=0
(3x+8)(x+2)=0
x=-8/3 or -2

Answer: 10.99</h3>
Work Shown:
Angle B = 20 is the reference angle
AC = 4 is the side opposite this reference angle
BC = x is the unknown adjacent side
tan(angle) = opposite/adjacent
tan(B) = AC/BC
tan(20) = 4/x
x*tan(20) = 4
x = 4/tan(20)
x = 10.9899 approximately (make sure your calc is in degree mode)
x = 10.99 rounding to two decimal places
BC = 10.99
B - 4.2 < -7.5
subtract b and 4.2
less then sign is <
then <-7.5
