Answer:
A
Step-by-step explanation:
Note the expansion
tan(a - b) = 
We are given the right side of the expansion , then left side is
tan(
- 
)
= tan(
)
= tan (
) → A

I hope this is good enough:
One number is 4 times the other, so x and 4x.
The sum of two numbers is 4x+x=70.

the other number is 4x=4*14=56
Answer:
- after the raise, her salary is $1755 per month
- this is a +17% change from her original salary
Step-by-step explanation:
The multiplier of her original salary to her reduced salary is ...
(1 - 10%) = 0.90
The multiplier of her reduced salary after her raise is ...
(1 +30%) = 1.30
The multiplier of her raised salary from her original salary is ...
(0.90)(1.30) = 1.17 = (1 +17%)
Her salary after the 17% raise is ...
1.17·1500/mo = $1755/mo
