Answer:if you want grams than use metric if pounds use standard
Step-by-step explanation:
The given expression is a difference of squares, so we have
16 (<em>a</em> + <em>b</em>)² - 49 (<em>a</em> - <em>b</em>)² = 4² (<em>a</em> + <em>b</em>)² - 7² (<em>a</em> - <em>b</em>)²
… = (4 (<em>a</em> + <em>b</em>))² - (7 (<em>a</em> - <em>b</em>))²
… = (4 (<em>a</em> + <em>b</em>) - 7 (<em>a</em> - <em>b</em>)) (4 (<em>a</em> + <em>b</em>) + 7 (<em>a</em> - <em>b</em>))
… = (4<em>a</em> + 4<em>b</em> - 7<em>a</em> + 7<em>b</em>) (4<em>a</em> + 4<em>b</em> + 7<em>a</em> - 7<em>b</em>)
… = (-3<em>a</em> + 11<em>b</em>) (11<em>a</em> - 3<em>b</em>)
we are adding over 200,000 people<span> to this planet every day, or </span>140 people<span> every minute . That equals over </span>70 million<span> more people every year

Answer:
c. 107°
Step-by-step explanation:
In the figure attached, Circle P, segments AB and BC, and angle x are shown.
From circumscribed angle theorem, we know that angle ABC and angle x are supplementary, then:
x + 73° = 180°
x = 180° - 73°
x = 107°
