Answer:
Step-by-step explanation:
f(x) = -8x² + 7x³ + 2x - 5
= 7x³ - 8x² + 2x - 5 This meets the definition of a polynomial
Answer:
the total charged for a car is f(x)=x+5
Step-by-step explanation:
because ther is only on car the value 5 could be constant. but because there could be a number of people in the car that is described by x and is multiplied by the cost which is 1
area of square = 4ft²
a s area of square = length×lenght
let lenght =x
so area = x²
x²= 4ft²
taking square root
x=2 ftSo lebght of each side is 2 ft.
Answer:
f(x) = x*2+1
Step-by-step explanation:
Answer:
x=7.5
Step-by-step explanation:
Let's solve your equation step-by-step.
3(x+4.5)=36
Step 1: Simplify both sides of the equation.
3(x+4.5)=36
(3)(x)+(3)(4.5)=36(Distribute)
3x+13.5=36
Step 2: Subtract 13.5 from both sides.
3x+13.5−13.5=36−13.5
3x=22.5
Step 3: Divide both sides by 3.
3x/3=22.5/3
x=7.5
Answer:
x=7.5
