The expression which represents the side length of the square which has perimeter of 12x 52 units is 3x+12 units.
<h3>What is the perimeter of a square?</h3>
The measure of the boundary of the sides of a square is called its perimeter. The perimeter of a square is 4 times the side of the square.
Here, (<em>a</em>) is the side of the square.
A square has a perimeter of 12x +52 units. The perimeter of a square is 4 times the side of the square. Thus, the side of this square is,
Thus, the expression which represents the side length of the square which has perimeter of 12x 52 units is 3x+12 units.

Answer:
45
Step-by-step explanation:
To find the number you just add 6 to 39 which gets you 45.
The order of operations is PEMDAS. You would work on multiplying the -6 and 3.
Answer:
17.5
Step-by-step explanation:
as the triangles are similar, when oriented in the same direction they have the same angles, and the lengths of all sides of DEF are the lengths of the sides of ABC but multiplied by the same scaling factor f for all sides.
so, we see that
A ~ D
B ~ E
C ~ F
and therefore
AB ~ DE
BC ~ EF
CA ~ FD
that means
DE = AB × f
EF = BC × f
FD = CA × f
we know DE and AB.
so,
4 = 10 × f
f = 4/10 = 2/5
and now we know
EF = 7 = BC × f
BC = 7/f = (7/1) / (2/5) = (5×7)/(2×1) = 35/2 = 17.5
