<span>Expressing in simplest radical form just means simplifying a radical so that there are no more square roots, cube roots, 4th roots, etc left to find. It also means removing any radicals in the denominator of a fraction.</span>
Answer:
9 hours
Step-by-step explanation:
If there's 4 people, they each need 1.5h So you multiply 1.5 by 6 and that's how you find how long it takes for 1 person.
Answer:
6.7
Step-by-step explanation:
let n = the number
3n + 9 = 29
3n = 20
n = 20/3 or 6.67
8a+2b * -2a + 5b (since there's an invisible -1, at least the 1 is) so the product of that is -16a^2 + 10b^2
Answer:
A = π(34), or approx. 106.8 units²
Step-by-step explanation:
Recall that the formula for the area of a circle is A = πr².
If (3, 5) is a point on the circle at hand, then the radius (found using the Pythagorean Theorem) is r = √(3² + 5²) = √(9 + 25) = √34.
Then r² = 34, and the area of this circle is
A = π(34), or approx. 106.8 units²
