Answer:
7a-3b
Step-by-step explanation:
(10a-7b) - (3a-4b)
Subtract like terms:
10a-3a = 7a
-7a--4b = -3b
Put together:
7a-3b
Radius of the circular tent (r) = 3 m
Area of the floor = Area of circle =

r²

= 3.14
Area of the floor = 3.14 x 3² = 28.26 m²
Answer:
10v^{10}
Step-by-step explanation:
Answer:
alternate exterior angles converse
Since were Pythagorean theorem, you would have to do a2 + b2 = c2 then when you find c2, you divide it by the power of 2.
With this case, a2 would be 9 since 3 by the power of 2 is 9.. B2 would be 49 since 7 by the power of 2 would be 49 With these two numbers, we get 58.
With 58, you divide it by 2. After this, you would get c ≈ 7.62
