Answer:
<h2>3x^2+2x−4=0</h2>
Use the quadratic formula to find the solutions
−b±√b^2−4(ac)/2a
Substitute the values
a=3, b=2, and c=−4 into the quadratic formula and solve for x.
−2±√2^2−4⋅(3⋅−4)/2⋅3
Simplify.
x = −1±√13/3
The final answer is the combination of both solutions.
x= −1−√13/3,−1+√13/3
The result can be shown in multiple forms.
Exact Form:
x= −1−√13/3,−1+√13/3
<h3>Decimal Form:</h3>
x=0.86851709…,−1.53518375…

y=53
x=(53)-45
x=8
Answer:
A, B, C are correct
Step-by-step explanation:
m∠T is the complement of ∠C, so is 90° -16.7° = 73.3° . . . matches C
The lengths of the sides are ...
t = a·cos(16.7°) = 49·0.957822 ≈ 46.93 . . . matches B (not D)
c = a·sin(16.7°) = 49·0.287361 ≈ 14.08 . . . matches A
