It says that the terms are increasing by 3 every time.
The 'number 1' term is 7.
So, the 'number 0' term would be 7-3=4.
So, the expression is 3n+4
Answer:
You have to add the perimeter of + 4 and 5 + 1.
Step-by-step explanation:
Remember when it says "area" that means multiply but "perimeter" means addition.
This is an easy way to solve multiplication with alot of zero's
Add only the numbers, then add the sum of the zeros
So with this problem we do this:-
5*4 is 20, plus the zero in the 50, so the answer is 200
Now we can do the other one:-
5*4 is 20, plus the 4 zeros that we removed is 200,000
Hope I helped. :)
Vertical angles are equal
5x - 40 = 3x + 8
5x - 3x = 8 + 40
2x = 48
x = 48/2
x = 24
m∠ABC = 3x + 8 = 3 * 24 + 8 = 80°
(or m∠ABC = 5x - 40 = 5 * 24 - 40 = 80°)
