i think it would be a model.
Step-by-step explanation:
Answer:
![\frac{5x+2}{(x-4)(x+7)}](https://tex.z-dn.net/?f=%5Cfrac%7B5x%2B2%7D%7B%28x-4%29%28x%2B7%29%7D)
Step-by-step explanation:
to obtain a common denominator
multiply the numerator/denominator of the first fraction by x + 7
multiply the numerator/denominator of the second fraction by x - 4
=
+
simplify and add numerators leaving the common denominator
= ![\frac{2x+14+3x-12}{(x-4)(x+7)}](https://tex.z-dn.net/?f=%5Cfrac%7B2x%2B14%2B3x-12%7D%7B%28x-4%29%28x%2B7%29%7D)
= ![\frac{5x+2}{(x-4)(x+7)}](https://tex.z-dn.net/?f=%5Cfrac%7B5x%2B2%7D%7B%28x-4%29%28x%2B7%29%7D)
Answer:
2100 miles.
Step-by-step explanation:
Given:
Diameter to the moon = 240000 miles
∅ = 0.5 °
The subtended angle by an arc is given as:
S = r∅
Where
r = radius of the circle
Therefore,
D = 240,000 x (0.5 x π rads)/180
= 2094 miles
= 2100 miles.
