Answer:
a=9.4cm
b=12.0cm
Step-by-step explanation:
Answer:
50
Step-by-step explanation:
the numbers are decreasing by 3 and 3 times 34 is 102
152- 102= 50
lmk if im wrong so i can fix it
EDIT: Its wrong dont use that answer lol
Remember

the key is that the base is the same
(12³)(11³) cannot be added
you have to understand how exponents work
12³=12*12*12
11³=11*11*11
so
if we had (12³)(11³), that is equal to 12*12*12*11*11*11
if we tried to add the expoennts, we would get 6, but would it be 12⁶ or 11⁶?
neither
so that's why the exponents can't be added, it's because they have different bases. we need to have the same base to add exponents
Do you know what complementary and supplementary angles are
Answer:
25 degrees
Step-by-step explanation:
Angles 4 and 6 are supplementary angles since they as same side interior angles for parallel lines cut by a transversal. This means angle 4 + angle 6 = 180. If angle 6 is 155 then angle 4 must be 25 degrees
