Answer:
5x^2 -3x +9
Step-by-step explanation:
To subtract, line up the common terms. I add a 0 term to keep the terms in line.
5x^2 + 0x +7
- (0x^2 +3x- 2 )
------------------------
Distribute the negative sign.
5x^2 + 0x +7
- 0x^2 -3x + 2
------------------------
5x^2 -3x +9
A constant in an algebraic expression is defined as a term that does not change during the expression, so, in other words, a term that does not have a variable in it. so the constants are
12
-3.7
1/3
30 ounces of water for 5 teaspoons of lemon
If you multiply length times width to get area, it's the same with division. You do area divided by length or width. The equation would be 225 divided by 13 3/4. 225/13 3/4= 16.36 inches. 16.36 > 16 inches, so the answer would be no. (The mirrors length and width are 13 3/4 inches by 16 9/25)
I think you are missing part of the problem. If you had another equation or a value for x you could solve it.
