Answer:

Step-by-step explanation:

+ We find the function (f+g)(x) like

(f+g)(x)= f(x) + g(x) = x^2 +3x+5 + x^2 + 2x = 2x^2 +5x + 5

+ So the graph of (f+g)(x) is a parabole with the sommet (-5/4, 15/8).

Hope that useful for you.

I made a fort for my pet porcupine by connecting two boxes. the first box is 10 meters long, 7 meters wide, and 5 meters high. t
Lerok [7]

First, let's find the volume of the two boxes.

V = lwhV=lwhV, equals, l, w, h

V=10\times7\times5V=10×7×5V, equals, 10, times, 7, times, 5

V= \blue{350} \text{ cubic meters}V=350 cubic metersV, equals, start color blue, 350, end color blue, space, c, u, b, i, c, space, m, e, t, e, r, s

V = lwhV=lwhV, equals, l, w, h

V=4\times10\times8V=4×10×8V, equals, 4, times, 10, times, 8

V= \pink{320} \text{ cubic meters}V=320 cubic metersV, equals, start color pink, 320, end color pink, space, c, u, b, i, c, space, m, e, t, e, r, s

Hint #22 / 3

Since my porcupine can play in both boxes, we need to add the volumes of the two boxes.

\blue{350}+\pink{320}=\green{670}350+320=670start color blue, 350, end color blue, plus, start color pink, 320, end color pink, equals, start color green, 670, end color green

Hint #33 / 3

My porcupine has \green{670}670start color green, 670, end color green cubic meters of space to play in his fort.  

670 is your answer i hoped this help please rate me thanks :)
