It would be B. 11 is bigger then 6
Add like terms
I'm assuming that you forgot to put the parenthasees at the end
so exg
4x+8x=12x
2x^2+3x^2=5x^2
3x^2+3x^3=3x^2+3x^3
group like tems
6x^3+9x-8+5x-9x^2+7
6x^3-9x^2+14x-1
Answer:
The number is 7.
Step-by-step explanation:
4n - 7 = 21 Add 7 on both sides
4n = 28 Isolate the variable by dividing 4 on both sides
n= 7

Since we know that x% is x/100, then </span>
14 1/2 % can be expressed as:
14 1/2% = 14.5% = 14.5/100 = 0.145
AC= 20!! simply use the pythagorean theorem. 15 squared + b squared = 25 squared. 225 + b squared = 625. b squared= 400, b=20, AC=20.
