Answer:

Final answer is f(x)+g(x)=0.5x^2+8x^3

Step-by-step explanation:

Given functions are f\left(x\right)=0.5x^2-2 and g(x)=8x^3+2

Now we need to add both functions:

f(x)+g(x)

=(0.5x^2-2)+(8x^3+2)

=0.5x^2-2+8x^3+2

=0.5x^2+8x^3-2+2

combine like terms -2 and +2

=0.5x^2+8x^3

Hence final answer is f(x)+g(x)=0.5x^2+8x^3

<u>Answer:</u>

f ( x ) + g ( x ) = 8 x^3 + 0.5 x ^2

<u>Step-by-step explanation:</u>

We are given the following two functions and we are to find their sum:

f ( x ) = 0.5 x ^ 2 - 2

g ( x ) = 8 x ^ 3 + 2

Adding the two given functions to get:

f ( x ) + g ( x ) = 0.5 x ^ 2 - 2 + 8 x ^ 3 + 2

Rearranging them to solve further:

f(x)+g(x) =8x^3+0.5x^2+2-2

So finally we get:

f(x)+g(x) =8x^3+0.5x^2

Answer/Step-by-step explanation:

Statement 1: \overline{AD} = \overline{RC}

Reason 1: Given

Statement 2: <A ≅ <R

Reason 2: Given

Statement 3: <AMD ≅ <RMC

Reason 3: vertical angles

Both angels are vertical angles. Vertical angles are congruent to each other. Therefore, <AMD ≅ <RMC.

Statement 4: ∆MAD ≅ ∆MRC

Reason 4: AAS Congruence Theorem

Two angles and a non-included side in ∆MAD are congruent to corresponding two angles and a non-included side in ∆MRC. Based on the AAS Congruence Theorem, both triangles are congruent.

Shana ran 6miles in 1 week. this is one third of what she ran in the month. let m represent the number of miles shana ran in a l
Slav-nsk [51]
Let m be the distance (in miles) she runs in a month
and w be the distance (in miles) she runs in a week

since the total distance she run in a week is one third of what she run in a month, in equation form
w = m/3

to calculate the distance she run  in a month,
m = 3w
m = 3(6 miles)
m = 18 miles in a month
