You need to find the sum of the areas of the 6 sides.
That will be:
2*10*5+2*5*4+2*4*10=220
The equivalent expression is (g - f) (3) = 23
<em><u>Solution:</u></em>
Given that,
To find: (g - f)(3)
We know that,
(g - f)(x) = g(x) - f(x)
Substituting values we have:
Rewriting we get,
Now let us evaluate for x = 3
Substitute x = 3 in above equation
Therefore the equivalent expression is (g - f) (3) = 23
Answer:
D. 4 is the non linear area of the graph.
Step-by-step explanation:
Non linear is when there is not a exact increase or decrease, also known as a equal change over time.
Answer:
12 is the answer.
Step-by-step explanation:
The best way to get the roots of the equation is to factorize the equation but when the factors are not possible then we should apply the quadratic equations formula to get the value of x.
Now we will try to factorize
x² - 8x -48 = 0
Now we multiply coefficient of highest degree term and constant term
48×1 = 48 which may be factored in 12×4. 8×6, 24×2.
Now we will choose 12×4 out of three because the 12-4 = 8 which is the coefficient of x.
Now its simple.
x²-12x + 4x -48 = 0
x(x -12) + 4(x-12) = 0
(x +4)(x-12) = 0
Therefore roots are x + 4 = 0
x = -4
and x - 12 = 0
x = 12
So the answer is 12.
