Answer:

step 2

Step-by-step explanation:

Given

p = 2l + 2w ( subtract 2w from both sides )

p - 2w = 2l ← correct step 1

Now, divide both sides by the multiplier 2

\frac{p-2w}{2} = l

The final exam of a particular class makes up 40% of the final grade, and Moe is failing the class with an average (arithmetic m
amm1812

Answer:

%82.5

Step-by-step explanation:

  1. The final exam of a particular class makes up 40% of the final grade
  2. Moe is failing the class with an average (arithmetic mean) of 45% just before taking the final exam.

From point 1 we know that Moe´s grade just before taking the final exam represents 60% of the final grade. Then, using the information in the point 2 we can compute Moe´s final grade as follows:

FG=0.40*FE+0.60*0.45,

where FG is Moe´s Final Grade and FE is Moe´s final exam grade. Then,

\frac{ FG-0.60*0.45}{0.40}=FE.

So, in order to receive the passing grade average of 60% for the class Moe needs to obtain in his exam:

FE=\frac{ 0.60-0.60*0.45}{0.40}=0.825

That is, he need al least %82.5 to obtain a passing grade.

Evaluate f(2) for the function f(x) = 3x² + 2x - 5.
Softa [21]

Answer:

f(2)= 11

Step-by-step explanation:

you have to substitute 2 for every x you see:

                       f(x) = 3x² + 2x - 5

                       f(2)= 3(2)^2+2(2)-5

                       f(2)= 11
