Answer:#1. 13, 18, 23, 28, 33, 38, 4, 48, 53
To generate the next term, add 5 to the previous term.
Step-by-step explanation:18-13=5 see if it is the same for the others and go from there.
The quotients are equal because they both go in the same number of times. The second pair of quotients just have an extra 0 at the end which just changes the place value of the number.
Answer:
I think Substitution
Step-by-step explanation:
Because x is already solved for in the second equation.
Answer:
52 units.
Step-by-step explanation:
If we drop a perpendicular line from point C to AD and call the point ( on AD) E we have a right triangle CED.
Now CE = 6 and as the whole figure is symmetrical about the dashed line,
ED = (26 - 10)/2
= 8.
So by Pythagoras:
CD^2 = 6^2 + 8^2 = 100
CD = 10.
So, as AB = CD,
the perimeter = 10 + 26 + 2(8)
= 52.
