Find the GCF of 207c^3 and 108c^2

geniusboy [140]

Answer: 9c²

Step-by-step explanation:

To find the Greatest Common Factor of 207c³ and 108c², first factor them down to their primes and see what they have in common.

207c³ 108c²

∧ ∧ ∧ ∧

9·23 c·c·c 9·12 c·c

∧ ∧ ∧

3·3 3·3 3·4

∧

2·2

207c³: 3·3·23 c·c·c

108c²: 2·2·3·3·3·4 c·c

GCF = 3·3 c·c

= 9c²

Which of these choices show a pair of equivalent expression? Check all that apply.

padilas [110]

Answer:

C and D

Step-by-step explanation:

using the rules of exponents

$125^{3/7}$ = $\sqrt[7]{125^3}$ ≠ $\sqrt[3]{125^7}$

( $\sqrt{12}$ )^7 = $12^{7/2}$ ≠ $12^{1/7}$

( $\sqrt{4}$ )^5 = $4^{5/2}$ ← correct

( $\sqrt{8}$ )^9 = $8^{9/2}$ ← correct

Answer:

20.6

Step-by-step explanation:

Coordinates given:

D(-3,2)
E(4,2)
F(4,-3)

Plotted, these points give a right triangle with hypotenuse DF

Distance DE = 4 - (-3) = 7
Distance EF = 2 - (-3) = 5
Distance DF = √(7²+5²) = √84 = 8.6

Perimeter

P = 7 + 5 + 8.6 = 20.6
