I’m pretty sure you set the perimeters equal to each other, it would look like 3x+8+3x+7+3x = 3x+3x+4x+2 and then you add the similar ones so it would look like 9x+15 = 10x+2 then you subtract the two from both sides and subject the 9x from both sides and get 13 = x
AB would be 47
BC = 46
AC = 39
PQ = 39
QR = 39
PR = 54
then you could double check
47+46+39 = 39+39+54
132 = 132
The answer is 18.
I hope this helps :D
Answer: 4 UNITS LEFT!!!
Step-by-step explanation: I know it!
Please give me brainiest
Hope I helped :)
Step 1.)
7x + 7 * 4.
We need to expand this term by multiplying a term and an expression.
The following product distributive property will be used:
A(B+C) = AB + AC
Numerical factors in this term have been multiplied.
In our example, the resulting expression will consist of 2 terms:
the first term is a product of 7 and x
the second term is a product of 7 and 4.
7x + (7 * 4)
Numerical factors in this term have been multiplied.
Which equals:
7x + 28
Hope you understand this and it helps. Have a great evening!
