Answer:
a = 7, b = 
Step-by-step explanation:
Using the sine ratio in the left right triangle and the exact value
sin45° =
, then
sin45° =
=
=
( cross- multiply )
a ×
= 7
( divide both sides by
)
a = 7
--------------------------------------------------------
Using the tangent ratio in the right triangle on the right and the exact value
tan60° =
, then
tan60° =
=
=
=
( multiply both sides by b )
b ×
= 7 ( divide both sides by
)
b =
×
=

Answer:
there's this one app called Photomatix that does any algebra problem
Step-by-step explanation:
Formula for simple interest:

where
a = final amount
p = principal amount
r = interest rate per annum
t = time in years
Now, we are finding a, the final amount, and given,
p = $650
r = 5.5% (5.5/100)
t = 4 years

(x² - 4x - 32) / (x² +7x +12)
factor both the numerator and denominator
[(x-8)(x+4)] / [(x+3)(x+4)]
Since (x+4) is in both the numerator and denominator, it can be cancelled out:
(x-8)/(x+3) is the simplified form
