Well, following the order of PEMDAS, I got choice B. 52
For instance, when you plug in 5 for x, you get F(5)=2(5)^2+2.
Moreover, following PEMDAS, you're supposed to solve what's inside the parenthesis, but since there is no operation going on inside the parenthesis, then you simple move on to the exponent.
In this case, you square the number 5, which gives you F(5)=2(25)+2
After that, you Multiply (letter M in PEMDAS). This results in F(5)=50+2.
Finally, you add them, which results in F=52.
By the way, I noticed a mistake in your work. When multiplying 2 by 5, the answer is 10, not 20.
Anyway, hope this helped! :-)
Answer:
0.322 × 10¹² /L
Step-by-step explanation:
Data provided in the question:
Number of cells counted with blue-stained granulofilamentous material
i.e number of RET = 100
The red blood cells count = 3.22 × 10¹² /L
Hematocrit = 30%
Now,
RET% = [ [ Number of RET ] ÷ 1000 RBCs ] × 100%
= [ 100 ÷ 1000 ] × 100%
= 0.1 × 100%
= 10%
also,
Absolute reticulocyte count = ( %RET × RBC count ) ÷ 100
= [ 10 × 3.22 × 10¹² /L ] ÷ 100
= 0.322 × 10¹² /L

Answer:
x = 1/2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
10−2x=19x+2−5x
10+−2x=19x+2+−5x
−2x+10=(19x+−5x)+(2)(Combine Like Terms)
−2x+10=14x+2
−2x+10=14x+2
Step 2: Subtract 14x from both sides.
−2x+10−14x=14x+2−14x
−16x+10=2
Step 3: Subtract 10 from both sides.
−16x+10−10=2−10
−16x=−8
Step 4: Divide both sides by -16.
−16x/−16 = −8/−16
x = 1/2
