Step-by-step explanation:
Answer:
the new one for a: 12/21 and 15/21
the new one for b: 20/25 and 15/25
the new one for c: 20/27 and 33/27
the new one for d: 25/24 and 36/24
Step-by-step explanation:
4/7 x 3/3 equals 12/21
3/5 x 5/5 equals 15/25
11/9 x 3/3 equals 33/27
6/4 x 6/6 equals 36/24
Answer:
A: 34 degrees
B: 102 degrees
Step-by-step explanation:
Complementary angles = 90 degrees
Supplementary angles = 180 degrees
(a) 90 - 56 = 34
(b) 180 - 78 = 102

Answer:
116
2
real
irrational
Step-by-step explanation:
discriminant= b^2-4ac
a=1 b=8 c=-13
discriminant = 8^2 -4*(-13)=64+52=116
if discriminant>0 then we have two real solutions
since √116 is not an integer, solutions are irrational
