Five consecutive integers are:
n, n+1, n+2, n+3, n+4 the sum of which is:
5n+10=265 subtract 10 from both sides
5n=255, divide both sides by 5
n=51
Our fifth number was n+4 so the fifth number is 55
The sign only changes when divided or multiplied by a negative number.
D(2, –4) → D' = (-4, 2)
E(1, –1) → E'= (-1, 1)
F(5, 1) → F'=(1, 5)
What is the rule that describes a reflection across the line y = x?
rx = y(x, y)= (y, x)
Answer:

Step-by-step explanation:
The area of a trapezoid is given by the average of the bases multiplied by the height.
What we're given:
- Height of 3
- Bases of 1 and 4
The average of the bases 1 and 4 is equal to 
Therefore, the area of the trapezoid is
