Answer: 361
Step-by-step explanation: 4(the change) times 93 (the term u want) minus 11 (your starting number/term)
Answer:
y = x^2 - 4x - 6.
Step-by-step explanation:
The roots are 2 + √10 and 2 - √10, so in factor form we have:
(x - (2 + √10))(x - (2 - √10))
= ( x - 2 - √10)(x - 2 + √10)
= x^2 - 2x + √10x - 2x + 4 - 2√10 - √10x + 2√10 - √100
= x^2 -4x + 4 - 10
= x^2 - 4x - 6.

5, 19, 21
Step-by-step explanation:
The sum of two smaller sides must be larger than the largest side in order to be a triangle. This means that only the first one can be a set of the triangle.
The surface area, SA, of a rectangular prism is given by the formula:
SA = 2ab + 2bc + 2ac,
where, a, b, and c are lengths of the 3 sides of the rectangular prism
For this problem, the surface area of the rectangular prism was given to be 208 cm². The two sides given can be assigned the variables, a = 2 cm and b = 10 cm. This leaves us with one side, c, as the unknown dimension. The resulting equation is as follows:
208 cm² = 2(2 cm)(10 cm) + 2(10 cm)(c) + 2(2 cm)(c)
c = 7 cm
