An acute triangle
Step-by-step explanation:
Using a calculator, these measurements fit an acute scalene triangle.
A is the answer, because the highest exponent is 2.
<u>quadratic</u>
A's expression foiled would be 2x^2 + x - 6
B's expression foiled would be 3x - 12, where the exponent on x is only 1.
D's expression foiled would be x^3 - x^2 - 12x, where the exponent on x is 3.
You'll have to subtract 5 on each side and that'll leave 3 ≥ 3x
Then you'll divide on both sides and flip the inequality: x ≤ 1
