Answer:

The GCF is 28

Step-by-step explanation:

<u>Step 1: Find the factors of both numbers</u>

84 → 1, 2 , 3 , 4 , 6 , 7 , 12 , 14 , 21 , 28 , 42 , 84

56 → 1 , 2 , 4 , 7 , 8 , 14 , 28 , 56

The factor that is the biggest common in both is the GCF. We see that 28 is the biggest factor that matches for both numbers.

Answer: The GCF is 28

(x-5)1/2+5=2<br> (x-5)1/2=-3<br> [(x-5)^1/2]^2=(-3)^2

Studentka2010 [4]

Answer:

x = 14

Step-by-step explanation:

You want to solve for x, right?

(x-5)^(1/2)+5=2

You have it right so far.

(x - 5)^(1/2) = -3

(x - 5) = (-3)^2

x - 5 = 9

x = 9 + 5 = 14

Please need help evaluate the math problems

x + y when x = 6 and y = 2

6 + 2 = 8

$\frac{9x+24}{4}$ when x = 12 and y = 20

$\frac{148}{4}$ = 37

$\frac{6m}{n}$ when m = 12 and n = 3

$\frac{72}{3}$ = 24

Six times x

Six increased by x

6 + x

The sum of x and y

x + y
