Answer:
9. B, C, D
10. A, D, E
Step-by-step explanation:
9. A. Students who bring lunch do not represent cafeteria purchases.
B. - D. Are randomized.
10. A. 1/4 of 50 is 12.5. about equal to 12
B. 12% of 50 is 6. not equal to 12
C. 12 ÷ 50 = 24. 3,000 × 0.24 = 720. not less than 500
D. (see above work) 720 = 720
E. 3,000 - 720 = 2,280. more than 2,000
6x+5=5x+8+2x
Add 2x to 5x
6x+5=7x+8
Subtract 6x from both sides
5=x+8
Subtract 8 from both sides
Final Answer: -3=x
And so no, -5 is not the solution to this equation.
The surface area of the box is bigger than the <em>surface area</em> of the available wrapping paper. <em>Thus, you don't have enough wrapping paper to wrap the gift box.</em>
The given parameters;
- area of the wrapping paper available, A = 275 square inches
- volume of the gift box, V = 343 in²
First, determine the length of each side of the box;
The length of each side is represented with x;
x³ = 343
![x = \sqrt[3]{343} \\\\x = 7 \ inches](https://tex.z-dn.net/?f=x%20%3D%20%5Csqrt%5B3%5D%7B343%7D%20%5C%5C%5C%5Cx%20%3D%207%20%5C%20inches)
Second, find the surface area of the box;
surface area of the box, A = 6x²
A = 6(7)²
A = 294 in²
The surface area of the box is bigger than the <em>surface area</em> of the available wrapping paper. Thus, you don't have enough wrapping paper to wrap the gift box.

Hey there!
b^2 - 5b + 3
= -3^2 - 5(-3) + 3
= -9 - (-15) + 3
= -9 + 15 + 3
= 6 + 3
= 9
Answer: 9
Good luck on your assignment and enjoy your day!
