It’s D.) 2n-8 hope this helps
The whole number could be 1 and 1/5 or 1.2
Answer:
first, subtract 17 on both sides: x²+2x-16=0
this cannot be factored, so use the quadratic formula to solve for x:
b²-4ac=2²-4(10(-16)=4+64=68
√68=2√17
so x=(-2+2√17)/2 or x=(-2-2√17)/2
x=-1+√17 or x=-1-√17
Step-by-step explanation:
I believe 22. Because 11+3=14, but without that, you would add 11 to 11, which gives you 22
