Answer:
14 headphones
Step-by-step explanation:
Use algebraic manipulation. Let x be the number of headphones sold this week:
89 = x + (3x + 5)
Combine like terms:
89 = 4x + 5
Get the x's on one side:
84 = 6x
Divide:
14 = x
So, Veronica sold 14 headphones this week.
Answer:
B
Step-by-step explanation:
Using the pythagorean theorem A^2 + B^2 = C^2 the only numbers that work are those in choice B. 8 short leg, 15 long leg, 17 hypotenuse.
8^2 + 15^2 = 17^2 = 64 +225=289 = 289=289 therefor proving these set of numbers are a right triangle.
The answer is. looks like c is the trig answer
