Answer:
Square: 
Vertex: (10,-68)
Step-by-step explanation:
For this case, we must clear variable "x" from the given equation, expressed in terms of "a".
We have:
3/a x-4=20
By clearing "x" we have:
Adding 4 to both sides of the equation:
3/a x = 20 + 4
Multiplying by a/3 on both sides of the equation:
x=24a/3
x=8a
So, x=8a
Answer:
x=8a
Answer:
A≈110.11
using formula 1/4
Step-by-step explanation:
Answer:

Step-by-step explanation:
We want to solve the equation:

Over the interval [0, 2π).
First, notice that this is in quadratic form. So, to make things simpler, we can let <em>u</em> = cos(x). Substitute:

Rearrange:

Factor:

Zero Product Property:

Solve for each case:

Back-substitute:

Using the unit circle:

Answer:
Step-by-step explanation:
If Frank is planting b seeds in one and 5b + 10 in the other, the expression showing the total is b + (5b + 10), or 6b + 10 seeds.
