Zepler [3.9K]

Answer:

$\large\boxed{(f+g)(x)=5x^2+6}$

Step-by-step explanation:

$(f+g)(x)=f(x)+g(x)\\\\f(x)=4x^2+1,\ g(x)=x^2-5\\\\\text{Substitute:}\\\\(f+g)(x)=(4x^2+1)+(x^2-5)\\\\=4x^2+1+x^2-5\qquad\text{combine like terms}\\\\=(4x^2+x^2)+(1+5)\\\\=5x^2+6$

0.7w + 16 +4 =27.28

stiks02 [169]

Answer:

w = 10.4

Step-by-step explanation:

step 1 - You add 16 and 4 which is 20

Step 2 - Than you subtract 20 from both sides so it will be 20 - 20 = 0 and 27.28 - 20 = 7.28

Step 3 - Now you take 7.28 ÷0.7 = 10.4

So the answer is 10.4
