Answer:
-2-12x-16
Step-by-step explanation:
(2x+4)(-x-4)
-2-12x-16
Answer: 74
Step-by-step explanation:
Lets say the four even numbers are 2x - 4, 2x - 2 , 2x , 2x + 2
The sum would be
8x - 4 = 284
x = 36
Therefore, the smallest number is 2 * 36 - 4 = 68
The consecutive even numbers are 68, 70, 72, 74 and 74 is the largest.
7. Straight lines are also = to 180°
If you look at the diagram, when you add the two angles together, they form a straight line.
Since the angles add up to 180°, you can do:
(x + 25)° + (4x + 5)° = 180°
x + 25 + 4x + 5 = 180 Combine like terms
5x + 30 = 180 Subtract 30 on both sides
5x = 150 Divide 5 on both sides
x = 30
