Perimeter is 2l+2w in the case of a rectangle, so you would write:
2(4x - 4.25) + 2(7x +7)
Answer:
20
Step-by-step explanation:
By HL and CPCTC, GF = FI, so GI = 2FI = 2(10) = 20.
I think its c
Step-by-step explanation:
Yes they are proportionate
The value of x would be 5 for the model 2x+4.
Rearrange unknown terms to the left side of the equation,

Combine like terms
By calculating the sum or difference : -x = -5
Lets divide both sides of the equation by the resulting coefficient 5
So x = 5
