Step-by-step explanation:
3x^2-(24+9)x+72=0
3x^2-9x-24x+72=0
3X(x-3)+24(x-3)=0
(x-3)(3x+24)=0
Step-by-step explanation:
A. Right
B. Acute
C. Right
D. Obtuse
Answer:
It's the third option
Step-by-step explanation:
the domain is all the x values
You will use the formula A=lw to find the area. Substitute 2x^3 in for the length and 4x^2 for the width. You would multiply both of these. 2×4 = 8, and x cubed times x squared equals X to the fifth power. You will add the exponents together because the exponent tells you how many times to multiply that value. If there are three x multiplied together (in x cubes) and two x multiplied together(in x squared) that makes five x multiplied together. The answer is represented as A=8x^5. ^ means to the power of.
