Good morning ☕️
Answer:
<h2>x² + 7x - 7</h2>
Step-by-step explanation:
f(x)=7x-3 and g(x)=x²-4
(f+g)(x) = f(x) + g(x) = 7x - 3 + x²- 4
= x² + 7x - 7

The domain is (-∞,∞)
the range is (−∞,2]
It would be 45.72 cm by 55.88 cm because you have to multiply each dimension by 2.54 to get the exact measurement in centimeters.
If the legs are length a and b and hyptonuse is c then
a²+b²=c²
so
if the legs are 20 and 21 and the hypotnuse is x then
20²+21²=x²
400+441=x²
841=x²
29=x
