Given:

The expression is 5+4\times 2+6-2\times 2-1.

To find:

The position of parentheses inserted in the expression to get the value 19

Step-by-step explanation:

We have,

5+4\times 2+6-2\times 2-1

Now,

(5+4)\times 2+6-2\times 2-1=9\times 2+6-4-1

(5+4)\times 2+6-2\times 2-1=18+6-5

(5+4)\times 2+6-2\times 2-1=18+1

(5+4)\times 2+6-2\times 2-1=19

There are more ways to apply the parenthesis, but we do not get 19.

5+4*\left(2+6\right)-2*2-1=32\neq 19

5+4*2+\left(6-2\right)*2-1=20\neq 19

5+4*2+6-2*\left(2-1\right)=17\neq 19

And many more possibilities.

Therefore, the expression after inserting the parentheses is (5+4)\times 2+6-2\times 2-1.

Let f(x) =-2x-7 and g(x)=-4x+3 find (f•g)(-5)
Ierofanga [76]
F(-5) x g(-5)

f(-5) = -2(-5) - 7
f(-5) = 10 - 7
f(-5) = 3

g(-5) = -4(-5) + 3
g(-5) = 20 + 3
g(-5) = 23

f(-5) x g(-5) = 3 x 23 = 69

Your answer is 69
