F(x) = 2x² + 7x - 5
g(x) = -8x² - 3x + 5
g(x) + f(x) = -8x² - 3x + 5 + 2x² + 7x - 5 = - 6x² + 4x
Answer: -6x² + 4x

"seven" means ' 7 '
"two" means ' 2 '
"the quantity seven plus two" means ' (7 + 2) '
"one hundred times the quantity ..." means ' <em>100 (7 + 2)</em> '
That's the expression.
One of the rules for handling these things is that you should always
take care of anything inside parentheses first. So do that.
(7 + 2) = 9
Now you can can write the expression like this: ' 100 (9) ' .
That's just <em>900 .
</em>
Since this is a right triangle, a triangle with a 90 degree-angle, we can use the trigonometric functions. An example would be the sine function. With respect to the angle, it has the opposite side (o), the adjacent side (a), and the longest side called hypotenuse (h). For the sine function, it would be sine theta = opposite/hypotenuse. Using this relationship,
sin 38 = BC/5
BC = 5*sin38
BC = 3.08 units
