Answer:
Linear expression
Step-by-step explanation:
If you have an expression with = sign, it becomes an equation
Without the = sign, it's just an expression
X^2+10x+21/x+3? If you meant (<span>x^2+10x+21)/(x+3), please note that those parentheses are essential.
If you wish to divide </span><span>x^2+10x+21 by (x+3) using synth. div., use the divisor -3:
_______________
-3 / 1 10 21
-3 -21
-----------------------
1 7 0
Since the remainder is 0, (x+3) is a divisor of </span><span>x^2+10x+21, and the other factor is (1x + 7).</span><span>
</span>
-- Write a fraction with whole numbers on top and bottom.
or
-- Write down any number, using only digits ... and a fraction bar or decimal point if you need them. If you write down the complete number, it's rational.
Consider rectangular box with
- length x units (x≥0);
- width 3 units;
- height (8-x) units (8-x≥0, then x≤8).
The volume of the rectangular box can be calculated as

In your case,

Note that maximal possible value of the height can be 8 units (when x=0 - minimal possible length) and the minimal possible height can be 0 units (when x=8 - maximal possible length).
From the attached graph you can see that the greatest x-intercept is x=8, then the height will be minimal and lenght will be maximal.
Then the volume will be V=0 (minimal).
Answer: correct choices are B (the maximum possible length), C (the minimum possible height)
