Answer:
f(-4) = 72, f(x + 5) = 3x² + 23x + 36
Step-by-step explanation:
f(-4) = 3(-4)² - 7(-4) - 4
= 48 - (-28) - 4
f(-4) = 72
f(x + 5) = 3(x + 5)² - 7(x + 5) - 4
= 3(x + 5)(x + 5) - 7(x + 5) - 4
= 3(x² + 10x + 25) - 7(x + 5) - 4
= 3x² + 30x + 75 - 7x - 35 - 4
f(x + 5) = 3x² + 23x + 36

Step-by-step explanation:
Let calories present in apple = x
Then as per the question, calories present in banana= 2x-15
Total calories = 141
x+2x-15=141
3x= 141+15
3x= 156
x= 52
Calories present in apple = 52 calories
Calories present in banana = 2(52)-15
= 104-15= 89
The mathematical equation for this word problem would be . . .
3/4 / 8
This equation also equals . . .
3/4 * 1/8
Then you would multiply the numerators together and the denominators together . . .
3 * 1/4 * 8
This simplifies to . . .
3/32
So, each student can get 3/32 of the cake.
Answer: 3/32 of the cake
