Answer:
sorry idk
Step-by-step explanation:
If she paid for 12 months for each answer the totals would be.
A= 528
B= 576
C= 624
D= 648
secA=√2
secA=sec45
A=45°
3cos²45+5tan²45/ 4tan²A-sin²45
= 3(1/√3)²+5(1)² / 4(1)²-(1/√2)²
=3/2+5/4-1/2
=13/7
Answer:
5 1/2 is your second answer :)
From the order of operations, we do parens, then multiply/divide, then add/subtract, rewriting each step to keep everything clear:
(14) - 2 - (50 ⋅ 2) <span>⋅ 1 - 1
14 - 2 - 100 </span><span>⋅ 1 - 1 [parens are finished]
14 - 2 - 100 - 1 [multiplication is finished]
-- we do the subtraction left to right, but here are the steps:
12 - 100 - 1
-88 - 1
-89</span>
