$96(2 payments) = $192
$192/(12 months) = $16 per month (she should set aside)
Answer:
Step-by-step explanation:
Remove the parentheses and take out the constansts.
Simplify 7 x 3 to 21.
Use the product rule: 
Simplify 2+5 to 7.
Simplfiy 3 + 8 to 11.
STU + STR = 180
8x + STR = 180 [ STU = 8x ]
STR = 180 - 8x
STR = SRT [ RS ≈ ST ]
Now, In ΔSRT,
we have, RST = 7x - 54, STR = SRT = 180-8x
Their sum is 180, as it constitutes a triangle.
7x-54 + 2(180-8x) = 180
7x - 54 + 360 - 16x = 180
306 - 9x = 180
9x = 306 - 180
9x = 306 - 180
x = 126/9
x = 14
So, option A is your answer.
Hope this helps!
(not sure if this is right but)
x (to the 2nd power) + y (to the 2nd power) = cos (90) (to the 2nd power)
