Answer:
9x^3 y^5
Step-by-step explanation:
Since the formula to finding area is (L*W = A), we first have to find the width.
Width: 3x^3 y^5 times 2 = 6x^3 y^5
Then we add them. So, 3x^3 y^5 + 6x^3 y^5 = 9x^3 y^5
Part A: 3x + 15 = 5x - 25
Part B: x = 20
Answer:
or, y + 4 = m (x - 7) + c is the given equation.
Step-by-step explanation:
Here, the slope of the equation = -5
⇒m = -5
The given point is (7, -4)
⇒
Now, the general form of the equation is :
: c = arbitrary constant
So, the given equation becomes
or, y+ 4 = m (x - 7) + c is the given equation.
Here, m = the slope of the equation.
