Answer:
area of trapazoid= 1/2 × b× h
so = 1/2×9×15
=1/2×135
=67.5cm
I'm not good with intigers, but if you added two negative intigers together wouldn't it still be negative? If you added -1 to -2 you'd get -3. It would always be less than the two original integers.
Answer:
Step-by-step explanation:
Hint: 1- 2sin²x = Cos 2x
LHS = 1 - 2Sin² (π/4 - Ф/2)
= Cos 2 *(π/4 - Ф/2)
= Cos 2*π/4 - 2*Ф/2
= Cos π/2 - Ф
= Sin Ф = RHS
Answer:
D option is correct
( At Q3 the market is wasting society's .. )
You distribute the number outside the parenthesis from the inside like the 3 to the q and the 3 to the 1 then the -4, add 1 and -4 which becomes -3 but then leave the one with the variable so it becomes 3q-3. do the same for each problem and the one with the fraction i suggest converting it to decimals so it's easier.
