Answer:
18
Step-by-step explanation:
16 × 9 = 8 × x
x = 18
Red blood cell, as they have a biconcave shape and need to store a lot of haemoglobin, the pigment of blood
hope this helps! :)
3x^2+12x+15=0
Then divide by 3 to get the x by itself.
x^2+4x+5=0
Factor to (x+5) (x-1) and solve for the two values of x.
I think this might be the answer since (a+b) equals 4, and ab= 3. I'm not sure.
a3 + b3
= (4)3+4(3)
= 12+12
= 24
