Answer:
9
Step-by-step explanation:
Multiplying the lengths of the intersecting pieces of the chords must be equal
3*6 = 2*x
18 = 2x
Divide each side by 2
18/2 = 2x/2
9=x
Answer:
x = - 4, x = 2
Step-by-step explanation:
Given
3x² + 6x - 24 = 0 ( divide through by 3 )
x² + 2x - 8 = 0 ← in standard form
(x + 4)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
x - 2 = 0 ⇒ x = 2
Answer:
x≥-6
Step-by-step explanation:
the set of all numbers for which a function is defined is called domain
for x≥-6 , this function is defined
Answer: 67°.
Step-by-step explanation:
1) m∠PMR=m∠LMN=3x+19°;
2) m∠LMN+m∠LMP=180°, it can be written as 3x+19+9x-31=180;
3) if to solve the equation 3x+19+9x-31=180, then x=16;
4) m∠PMR=3x+19=48+19=67°.
Answer:
12
Step-by-step explanation:
Do 1 divided by 4 and you get 0.25 then divide 3 and 0.25 and you get 12
