Find the value of the unknown numbers

4 →  b

-1 →  e

-4 →  a

-5 →  c

Step-by-step explanation:

From the given figure, we can find the values of a,b,c,d and e

To find a

3 - a = 7

a = 3 - 7 = -4

To find b

-1 - b = -5

b = -1 + 5 = 4

To find c

4 - c = 9

c = 4 - 9 = - 5

To find d

3 - d = 1

d = 3 + 1 = 4

To find e

-1 - e = 0

e = -1

There for the correct matching is given below

4 →  b

-1 →  e

-4 →  a

-5 →  c

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14

r = 78539458390583095803458309458039485093485 or just 3
