3p-(-20)=50
3p+20=50 subtract 20 from both sides
3p=30 divide both sides by 3
p=10
The area of a rectangle is shown through length times width. Being so, 13.7 times 10.5 equals 143.85 m^2.

the last one
x^2+2x+1 R(-5)
Answer:
x = 50
R = $2500
Step-by-step explanation:
Given in the question a quadratic equation,
−x² + 100x
To find the selling price, x, which will give highest revenue, y, we will find maximum value of parabola curve −x² + 100x
The value of -b/2a tells you the value x of the vertex of the function
−x² + 100x
here a = -1
b = 100
Selling price = -(100)/2(-1)
= 50
R = −(50)² + 100(50)
= 2500
