Answer: 49
Step-by-step explanation:
There would be 49 dots because each number is a square number. You skip 1 so every square‘s number is one less than the square root of the number of dots.

Answer:
The coordinates of point P are (-1, -1)
Step-by-step explanation:
The coordinates of the partition point (x, y) of a line segment whose endpoints are (x1, y1) and (x2, y2) at ratio m: n are
- x =
- y =
∵ P partitions segment HS in a ratio 2: 3
∴ P = (x, y)
∴ m = 2 and n = 3
∵ H = (5, -9) and S = (-10, 11)
∴ x1 = 5 and x2 = -10
∴ y1 = -9 and y2 = 11
→ Substitute them in the rule above to find x and y
∵ x = = =
∴ x = -1
∵ y = = =
∴ y = -1
∴ The coordinates of point P are (-1, -1).

Answer: 14x^2 - 84x - 7
====================================================
Explanation:
The like terms 6x^2 and 8x^2 combine to 14x^2
The like terms -8x and -76x combine to -84x
Nothing pairs with the -7, so its stays as is.
Standard form is where we list the terms in decreasing exponent order. We can think of -84x as -84x^1 and the -7 as -7x^0. So 14x^2 - 84x - 7 would be the same as 14x^2 - 84x^1 - 7x^0. The exponents count down: 2,1,0.
The final answer is a trinomial since it has three terms. It is also a quadratic because the degree (highest exponent) is 2.
