which expression is equivalent to 25 a. (8×4-2) ×3 +8 ÷ 2 b.8 x (4-2) ×3 + 8 ÷ 2 c. 8×4-(2×3+8)÷2 d.8×4- 2 ×3 + 8 ÷2

Answers

Answer 1

Answer:

Answer:

c. 8×4-(2×3+8)÷2

Step-by-step explanation:

Using the rules of BODMAS,

B stands for bracket

O stands for Order

D stands for Division

M stands for Multiplication

A stands for Addition

S stands for Subtraction

8×4-(2×3+8)÷2

Now using this rule we will first of all open the bracket, In the bracket we multiply then add

8 × 4 - (6 +8) ÷ 2

8 × 4 - 14 ÷ 2

Still applying the rule, we divide 14 by 2 to give us 7

8 × 4 - 7

Then, still applying the rule, we multiply 8 by 4 which will give us 32

32 - 7

Then we finally subtract 7 from 32 to give us 25

32 - 7 = 25

So the expression; 8×4-(2×3+8)÷2 is equivalent to 25

Answer 2

Answer: The answer is C.

Proof:
8×4-(2×3+8)÷2
=32-(6+8)÷2
=32-14÷2
=32-7
=25

Find the arithmetic combination of f(x) =x+2, g(x)=x-2

Answers

Answer:

The arithmetic combinations of given functions are (f + g)(x) = 2x, (f - g)(x) = 4, (f $*$ g)(x) = $\mathrm{x}^(2)-4$ , $\left((f)/(g)\right)(\mathrm{x})=(x+2)/(x-2)$

Solution:

Given, two functions are f(x) = x + 2 and g(x) = x – 2

We need to find the arithmetic combinations of given two functions.

Arithmetic functions of f(x) and g(x) are (f + g)(x), (f – g)(x), (f $*$ g)(x), $\left((f)/(g)\right)(\mathrm{x})$

Now, (f + g)(x) = f(x) + g(x)

= x + 2 +x – 2

= 2x

Therefore (f + g)(x) = 2x

similarly,

(f - g)(x) = f(x) - g(x)

= x + 2 –(x – 2)

= x + 2 –x + 2

= 4

Therefore (f - g)(x) = 4

similarly,

(f $*$ g)(x) = f(x) $*$ g(x)

= (x + 2) $*$ (x – 2)

= x $*$ (x – 2) + 2 $*$ (x -2)

$=x^(2)-2 x+2 x-4$

$=x^(2)-4$

Therefore (f $*$ g)(x) = $x^(2)-4$

now,

$\left((f)/(g)\right)(\mathrm{x})=(f(x))/(g(x))$

$=(x+2)/(x-2)$

$((f)/(g))(x)$ = $(x+2)/(x-2)$

Hence arithmetic combinations of given functions are (f + g)(x) = 2x, (f - g)(x) = 4, (f $*$ g)(x) = $\mathrm{x}^(2)-4$ , $\left((f)/(g)\right)(\mathrm{x})=(x+2)/(x-2)$
