T2 = t1 - 4 = 9 - 4 = 5
t3 = 5 - 4 = 1
The common difference = -4 so:-
The sequence is 9, 5, 1, -3, -7 ....
Answer:
Step-by-step explanation:
one piece is 60×60 inch
5 pieces each measuring 12×12
so total 6 patches on one side and 6 pieces back side of same dimension.
First you have to make the fractions equal.
That gives you 49/56 and 16/56.
Then you add them together and get 65/56.
So I guess she finishes the book. (not completly sure, werid)

Answer:
39
Step-by-step explanation:
For question number one
DBE has the measure x - 12
It is part of a 90 degree angle so to solve it we can use an equation.
2x - 12 = 90
2x = 102
x = 51
sub in the value to get 39.
Number two has a vertical angle so it has the same value as number one; 39
Number 3 is a 90 degree angle
