Answer:
21
Step-by-step explanation:
Similar triangles. MNL is just ABC but 3/4 the size.
x = 8*3/4 = 6
perimeter woudl be 6+6+9 = 21
Answer: D. 26 units
Step-by-step explanation: perimeter is the distance around the figure, or all the sides added together.
With a rectangle it is known that the opposite sides are congruent, or the same, so 8+8+5+5 = 26
48 = -18x is an equivalent expression because you just subtact -18 from both sides.
Since each of the sides of a square must all be the same length, the width and length of the square are both 5. The formula for the area of a square is
area = width * length
So that’s
area = 5 * 5
area = 25
