Answer:

5c^4( 9c^2 + 4).

Step-by-step explanation:

The GCF of 45 and 20 is 5 and the GCF of c^6 and c^4 = c^4.

So the GCF is 5c^4 and the factors are:

5c^4( 9c^2 + 4)

Answer:

5c^{4} (9c^{2} +4)

Step-by-step explanation:

First we factor out the lowest degree exponent (x^4) out of both sides.  

Then we can factor out the GCF of 45 and 20, which is 5.

We cannot factor anything else out of the equation, so the GCF would be 5c^{4} (9c^{2} +4c)

The process is shown below:

45c^{6} +20c^{4} \\= c^{4}(45c^{2} +20c)\\= 5c^{4} (9c^{2} +4)\\

A temperature of –25°c is equivalent to:<br> a. 248 k.<br> b. 25 k.<br> c. –25 k.<br> d. 298 k.
SpyIntel [72]

The temperature T in Kelvin (K) is equal to the temperature T in degrees Celsius (°C) plus 273.15:

T(K) = T(°C) + 273.15;

So, T(K) = -25 + 273.15;

T(K) = 248.15;

The correct answer is a.

The Census Bureau estimates that in 2020, 15 of the 50 states will have a Spanish-speaking majority. What percent of the states
Vinvika [58]
The answer is:  [C]:  "30%" .
_____________________________________________________
Explanation:
_____________________________________________________
Note that: "%" ; or "percent" means "out of 100" ; or "divided by 100" .
______________________________________________________
Method 1) 

15/50 = ?/ 100 ;

Look at the denominators:

50 * (what value?) = 100 ? ;  → "100 ÷ 50 = 2" ;

→ 50 * 2 = 100 ;

So:  "15/50 = (15*2)/(50*2) = "30/100" ; which is "30%" .
___________________________________________
Method 2:
___________________________________________
 "15/50" = (15÷5) / (50÷5) = 3/10 ; 

3/10 = (3*10) / (10*10) = 30/100 ; which is:  "30%" .
__________________________________________
Method 3:  (slight variation of "Method 2" above):
___________________________________________
 "15/50" = (15÷5) / (50÷5) = 3/10 ; 

3/10 = 0.3 = 0.30 = (0.30 * 100) % =  " 30% " .
