The area of a triangle is 3x3-16x²+9x+28 and the base is x-4. Use synthetic
1 answer:
Answer:
Step-by-step explanation:
If "3x3" is supposed to be 3x³, you need to use ^ to indicate that there is an exponent. 3x^3 = 3x³.
area = ½(x-4)(height) = (3x³-16x²+9x+28)
height = 2(area)/(x-4)
Using synthetic division, (3x³-16x²+9x+28) ÷ (x-4) = 3x²-4x-7
height = 2(3x²-4x-7) = 6x² - 8x- 14

Answer: x ≤ 15
Step-by-step explanation: All we need to do is divide both sides by 1/3, so1/3x / 1/3 and 5/ 1/3 = 15. So x ≤ 15.
Hope this helps!
