The formula to find it is 2(l x h + h x w + w x l) = SA in which l = length, h = height, and w = width.
Hope this helps!
Answer:
Dividing. Set up the equation. On a piece of paper, write the dividend (number being divided) on the right, under the division symbol, and the divisor (number doing the division) to the left on the outside. The quotient (answer) will eventually go on top, right above the dividend.
The answer to the question is c
Answer:
43
Step-by-step explanation:
You are going to want to substitute the x of the function f(x) with the function of g(x) and replace the x in g(x) with -4
(f+g)(-4) = 4+3((-4)^2-3)
=43

Answer:
3.) -x+4
4.)3/4x+3
5.)-3/5(x) -3
6.)-2x + 5
these are the "Slope intercept" forms of 3,4,5 and 6 you can learn to graph them as its hard for me to explain.
Step-by-step explanation:
3.) x+y=4, we want to write this in terms of y, so lets subtract x from both sides
y = -x+4 ----> this is in "slope intercept form" you can learn about this on "khan academy" as well.
4.) 3x-4y=-12 again we write in terms of y, subtract 3x from both sides.
-4y = -3x -12 then since we want y separately, we divide both sides by -4
y = 3/4(x) + 3 ------> if you didnt understand fully what i did to get to that, i divided everything by -4, and hopefully you know that a minus and a minus (multiplied or divided) will give a positive number.
5.) 3x+5y=-15 again we rewrite for y
5y = -3x - 15
y = -3/5(x) -3
6.) 2x+y = 5
y = -2x +5
the form in which y = whatever, is considered "slope-intercept form"
I cant really graph the points for you but watch this video, its very informative: https://www.khanacademy.org/math/algebra/two-var-linear-equations/graphing-slope-intercept-equations/v/graphing-a-line-in-slope-intercept-form
