D) 2.1+2x=7.5
All the sides added together will equal the perimeter
Answer: -1 and 5.
Step-by-step explanation:
x - 4x = 5 : Move the constant to the left.
x^2 - 4x - 5 = 0 : Rewrite the expression.
x^2 + x - 5x - 5 = 0 : Factor the expressions.
x(x+1) - 5(x+1) = 0 : Factor the expression.
(x+1)(x-5) = 0 : Seperate into possible cases.
x + 1 = 0, x - 5 = 0 : Solve the equations.
x = -1, x = 5 : The equation has 2 solutions.
Answer:
None of the above.
Step-by-step explanation:Yes, all of the sides match, which would make it an equilateral polygon. However, it is not an equiangular polygon because not all of the angels are the same. In this case, since the angles do not mach and only the sides do, this is not a regular polygon. This is what leads me to believe that is none of them. All of the sides must be congruent and all interior angles must also be congruent.
Answer:
42
Step-by-step explanation:
You can prove this by taking 42 and dividing it by 6, and you will see that the answer is 7. Tip: For future reference, when you are presented with a problem like "What divided by 6 equals 7?", all you have to do is multiply the two known numbers together.
