3/4 +4/5
find the common denominator which is 20
multiply by 5 for 3/4
(3)(5)/(4)(5)=15/20
multiply by 4 for 4/5
(4)(4)/(5)(4)=16/20
15/20+16/20
=31/20
answer:
31/20, 1 11/20 and 1.55

Answer:
~-1.67
Step-by-step explanation:
Multiply. Note that when you multiply a negative and positive number, your answer will be negative:
5 x (-1/3) = (5 * -1)/3
Multiply, then divide:
5 * -1 = -5
-5/3 = ~-1.67 (rounded to the nearest hundredths).

F(5) = - 2f(4) + 1
f(4) = -2f(3) + 1
f(3) = -2f(2) + 1
f(2) = -2f(1) + 1
Therefore:
f(2) = -2(3) + 1 = -5
f(3) = -2(-5) + 1 = 11
f(4) = -2(11) + 1 = -21
Therefore f(5) = -2(-21) + 1 = 43
There are 4 triangles, all in all.
The total interior angle is 180.
180 = 69 + 43 + (1)
(1) = 180 - 69 - 43
(1) = 68
180 = 112 + 41 + (2)
(2) = 180 - 112 - 41
(2) = 27
180 = 66 + 44 + (3)
(3) = 180 - 66 - 44
(3) = 70
180 = 109 + 29 - (4)
(4) = 180 - 109 - 29
(4) = 72
