Answer:
Step-by-step explanation:
area of a circle=πr^2
=3.14*(73)^2
=3.14*5329
=16733.06 ft^2
Answer: 
<u>Step-by-step explanation:</u>
Perimeter is the sum of the sides.
The length of AB is 3. The length of AC is 6. The length of BC can be found by using the Pythagorean Theorem: a² + b² = c²
3² + 6² = BC²
9 + 36 = BC²
45 = BC²
√45 = BC
3√5 = BC
Perimeter = AB + AC + BC
= 3 + 6 + 3√5
= 9 + 3√5
Simplifying that would be 3 * (-7) -10+25 = -6. Combining like terms will get us to -21 +15 = -6, going further will be -6 = -6. Remember Order of Operations. Since -6 = -6, the equation is true.
Answer is 7
plug in 4 for x in the g(x) equation and get 3, plug in 2 for x in the h(x) equation and get -4. then, 3-(-4)=7 because two negatives equal a positive
