-6p < 12 Divide -6 on both sides to get "p" by itself
p > -2
When you divide or multiply a negative number to both sides of the inequality, the sign (< , > , ≤ , ≥) is flipped.
PLEASE HELP !! c = 49 cm, a = 41°. Find B in degrees. Round to 2 decimal places.
1 answer:
Answer:
49.03 degrees
Step-by-step explanation:
c = 49, = 41
We can solve for if we first find b.
Remember: SOH CAH TOA
Cosine = Adj/Hypotenuse
So, Cos (41) = b/49
49 x (Cos 41) = b
49 x .755 = b
b = 36.99
sin = Opp/Hyp = b/49 = 36.99/49 = .755
β = inverse sin (.755) = 49.03° (Inverse sin is designated by sin⁻¹ on your calculator)

The solution to the equation x(x+4) = 6 is x = -2 + √10 or x = -2 - √10 after solving with the quadratic formula.
<h3>What is a quadratic equation?</h3>Any equation of the form where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:
We have an equation:
x(x + 4) = 6
By distributive property:
x² + 4x = 6
x² + 4x - 6 = 0
a = 1, b = 4, c = -6
Plugging all the values in the formula:
After calculating:
Thus, the solution to the equation x(x+4) = 6 is x = -2 + √10 or x = -2 - √10 after solving with the quadratic formula.
