Answer:
I think rhombus.
Step-by-step explanation:
Because a rhombus has all sides equal but no right angles. Squares and Rectangle both have right angles. And trapezoids have all different sides.
Separate the constant term from the rest of the expression.
2(x - 3)^2 = 90
Divide 2 on both sides.
(x - 3)^2 = 45
Take the square root of both sides.
x - 3 = +- sqrt(45)
x - 3 = +- 3 * sqrt(5)
x = 3 * sqrt(5) + 3
x = -3 * sqrt(5) + 3
Hope this helps!

the answer to number 7 is 1953152
Answer: A = 15 + 0.5(w)
Step-by-step explanation: The above equation represents the amount of dollars after selling w cups of water. Remember: we also have 15 in advance, so we add that to the total amount of cups sold. We multiply 0.5 (the amount earned per water cup) by w (the number of water cups sold) and we will get our answer.
To check this, let's say we sold 10 water cups. So w = 10. Therefore, we write A = 15 + 0.5(10). That = A = 15 + 5 which A = 20. We can use any number in place of w now and we will know it is correct using this formula
