In step 1, the commutative property of addition is used since x + 5 is just equal to 5 + x
In step 2, the associative property of addition is used since x is grouped to the last term.
In step 3, the distributive property of multiplication is used since 3 is multiplied to the terms inside the parenthesis.
In step 4, multiplication is done.
It would be 210,000 cause 2.5x20 = 50% so 420,000 x 50%
4×754=3016
4×4=16 4×5=20+1 4×7=30
this is the first method I mean this is the method that we are useing here in Macedonia
or maybe 754×4
The length is 1x+3 and the perimeter is 120
Y=(-11)^x
answer
when x is 1 y=-66
answer=-66
