1st: do distributive property, that will give you 3x + 6 + 5x
2nd: combine like terms to simplify, this will give you 6 + 8x
Answer:
Between each pair of points are coordinates K(x1,y1) F(x2, y2)
Distance KF =sqrt( (x2 - x1) ² + (y2 - y1) ²)
Step-by-step explanation:
Answer:
AD = 3
Step-by-step explanation:
Pythagoras theorem formula: a² + b² = c² (c being the hypotenuse, the longest side of the triangle).
Using this formula, you can easily say that c²-b²=a². c=5, b=4, making the equation 5² - 4² = a ².
Expanding the formula, you'll get 25 - 16 = a².
25 - 16 = 9.
This means that 9 = a².
To find a, you need to root 9. Using a calculator, you'll know that this number is 3, meaning that AD = 3.
It is the second answer:
8x²/y -2 is a solution which is equivalent to (8x²-2y)/2. Proof:
Reduce 8x²/y -2 to the same denominator:
8x²/y - 2y/y = (8x² - 2y)/y
Answer:
10 feet length and 6 feet width.
Step-by-step explanation:
If the total area of the patio is going to be equal to 60 square feet and the length is going to be 4 feet longer than the width, the dimensions that she should use for the patio are 10 feet for the length and 6 feet for the width which will equal to 60 square feet in total.
I hope this answer helps.
