Find the vertical and horizontal difference between the two given points:
Horizontal is the Y values: 4 - -4 = 4+4 = 8
Vertical is the X values 7 - -1 = 7+1 = 8
Multiply the changes by the ratio:
Now copy the dot on A 2 places to the left and down 2 places and the dot lands on point (5,2)
8 * 1/4 = 2
Answer:
14, 18, 20
Step-by-step explanation:
You have to replace the number in the "s" column with the "s" in the problem. For example the first number in the table is 2 so you have to put 2 into the problem then add it with 12 and you get 14.
280m is the area of the entire rhombus
We want to solve
x² + 8x + 7 = 0
Factorize the left side.
x² + 8x + 7 = (x + 1)(x + 7)
Therefore
(x + 1)(x + 7) = 0
When (x + 1) = 0, obtain x = -1.
When (x + 7) = 0, obtain x = -7.
The solutions are x = -1 and x = -7
Answer: x = -7 and x = -1.
