Answer:
450 cm
Step-by-step explanation:
25 on both sides 2x25
4 squares = 25x4
4 sides for 4 squares = 100x4
400+50
Answer:
8.
Step-by-step explanation:
As seen in the pattern y seems to be two times x so 4 x 2 = 8.
Hope that helps
Answer:
y= 2x -3
Step-by-step explanation:
The first thing you should know is that the slope of a perpendicular line is the opposite reciprocal. So, this is your current equation: y= 2x + b. Next, substitute your point into the equation to get the y-intercept. It should look like this: 9=2(6) + b. 6 times 2 equals 12. Now, this is what it should look like: 9=12 + b. Subtract 12 from both sides to get -3 = b. Go back to your original equation and plug in -3 to b. This is your final equation: y= 2x -3. Hope this helped!
