Answer:
Use the formula for the distance between two points: d = √((x2 – x1)2 + (y2 – y12))
Step-by-step explanation:
d = √((5 – 0)2 + (2 – 0)2
d = √(25 + 4) = √(29) ≈ 5.385
Answer:
x^3 +8x^2 +11x -20
Step-by-step explanation:
(x+5) * (x^2+3x-4)
Multiply x * (x^2+3x-4) = x^3 + 3x^2 -4x
Multiply 5 * (x^2+3x-4) = 5x^2+ 15x -20
Add -----------------------------------
x^3 +8x^2 +11x -20
To answer the equation first, let x be the number of pens. With this representation, the number of pencils she bought would be x - 4. The total amount she would have to spent for all the items is,
T = 6.70x + 3.5(x - 4)
Table a would be a function
You would want to go to the Montgomery County Fair because, since you only want to ride 5 rides, you will only pay $25 instead of $27.50. In other words you save $2.50
