Step-by-step explanation:
First you find the even amount of boys and girls out of 386
386 divided by 2 = 193
Then you subtract 32 boys and add the 32 to girls since there are 32 more girls than boys
(boys) 193 - 32 = 161
(girls) 193 + 32 = 225
So there are 161 boys and 225 girls

Answer:
292
Step-by-step explanation:
Given
f(x) = 6x²
g(x) = 3x + 4
Now.
f(4) = 6 * 4²
= 6 * 16

Now
g(f(4) = g( 96)
= 3 * 96 + 4
= 288 + 4
= 292
