If a=2b=3c=6, find the value of
a+2b-4c how to calculate this one

4

Step-by-step explanation:

Based on the equation you are given, calculate the values of a, b, and c. Then substitute each value for the corresponding variable and use the correct order of operations.

a = 2b = 3c = 6

a = 6

2b = 6, so b = 3

3c = 6, so c = 2

a + 2b - 4c =

= 6 + 2(3) - 4(2)

= 6 + 6 - 8

= 12 - 8

= 4

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
