Answer:
FCD
Step-by-step explanation: and sometimes we do not care about bold writing
FCD is the vertical angle I guess.
okay.
Hello there!
Pentagon = 5 sides.
For regular pentagon: 360/5 = 72. 180 - 72 = 108 degrees at each interior.
I hope this helps.
Answer:
A = x^2 + 5x - 14
Step-by-step explanation:
A = L × W
A = (x+7) × (x-2)
A = x^2 + 7x - 2x - 14
Answer:
The equation that can be used to solve for a is 1 = a(0=1)²-3.
Explanation:
In this case, I would model the parabola in vertex form. Vertex form is y = a(x-h)²+k, where (h,k) is the vertex of the parabola. Using the information from the question, we can plug in values to get 1 = a(0+1)²-3. (This could be simplified as 1 = a(1)²-3 ⇒ 1 = a-3 ⇒ a = 4, but we are only interested in finding the equation that can solve for a.)
