PLEASE help. The problem is to find the indicated sum.

alukav5142 [94]

The indicated sum is 350. The answer is 350 because the E or sigma is making you do (6j+2) ten times. Every time you do 6j+2 you start with j as 1 and add a 1 to j for every time you add. For example, [6(1)+2]+[6(2)+2]+[6(3)+2]...[6(10)+2].

Hope this helps.

Find the area of a parallelogram with a height of 2x - 3 and a base of x + 4.

saw5 [17]

Multiply the two as area is base times height.
$(2x - 3)(x + 4) \\ 2 {x}^{2} + 8x - 3x - 12 \\ 2 {x}^{2} + 5x - 12$

Use f(x)=(2x+1)/(3x-2) and g(x)=5x-1 to find <br> (gof)(x)

Orlov [11]

Answer:

From the functions f(x) and g(x) we have $(g\circ f)(x)=\frac{7(x+1)}{3x-2}$

Step-by-step explanation:

Given that the functions f is defined by $f(x)=\frac{2x+1}{3x-2}$

and g is $g(x)=5x-1$

To find the $(g\circ f)(x)$ :

$(g\circ f)(x)=g(f(x))$

$=g(\frac{2x+1}{3x-2})$

$=5(\frac{2x+1}{3x-2})-1$

$=\frac{10x+5}{3x-2}-1$

$=\frac{10x+5-1(3x-2)}{3x-2}$ ( by using the distributive property )

$=\frac{10x+5-3x+2}{3x-2}$

$=\frac{7x+7}{3x-2}$ ( adding the like terms )

$=\frac{7(x+1)}{3x-2}$

Therefore $(g\circ f)(x)=\frac{7(x+1)}{3x-2}$ .
