Answer:
B
Step-by-step explanation:
16/4=4
4x24=96
If this helps: 10 x .5 would be the same as 50% of 10. Also: 40 x .12 would be the same as 12% of 40.
We know <span>square of the sum <span>formula</span></span>
(a+b)²=a²+2ab+b²
so we need
x²+8x+c=(x²+2*4*x+4²)-16+c=(x+4)²+c-16,
so for full square we need c-16=0
c=16
Answer: c=16
