Answer:
18
Step-by-step explanation:
Sum the parts of the ratio, 3 + 4 = 7
Divide the amount of marbles by 7 to find the value of one part of the ratio
42 ÷ 7 = 6 ← value of 1 part of the ratio, thus
red marbles = 3 × 6 = 18
A percentage is out of 100.
85/100
in lowest terms this is
17/20
It has a rotational symmetry of 6
So minimum number of degrees = 360 / 6
= 60 degrees
Answer: In the resulting equation: " a² - 12a + 32 = 0 " ;

Explanation:
________________________________________________________
Let: "a = x² + 4 " .
Given: (x² + 4)² + 32 = 12x² + 48 ;
______________________________________________________
Factor: "12x² + 48" into " (x² + 4) " ;
"12x² + 48" = 12 (x² + 4) " ;
______________________________________________________
Given: (x² + 4)² + 32 = 12x² + 48 ;
rewrite as; "a² + 32 = 12a " ;
Subtract "12a" from each side of the equation;
"a² + 32 - 12a = 12a - 12a ;
to get:
" a² - 12a + 32 = 0 " .
___________________________________________________
The coefficient of the "a" term; that is:
The "coefficient" of " -12a" ; is: "- 12" .
The constant is: "32<span>" .
