Help please confused

A = 25

B = 27

C = 5

D = 15

E = 7

Step-by-step explanation:

The question states that all rows, columns, and diagonals have the same sum. With this assumption, we can add up 6, 16, and 26 to know that each row/column/diagnol adds up to 48. With this in mind, you can fill in the numbers needed to make all the rows add up to 48.

Example: A + 17 + 6 = 48, so A = 25

The more numbers you solve, the more knowledge you have to solve for the rest of the numbers.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
