Answer:
-72
Step-by-step explanation:
Answer:
B)
x units
Step-by-step explanation:
Let quadrilateral KMPT be a rectangle with dimensions 12 units by 8 units. Then its perimeter would be equal to:
Perimeter of a rectangle = 2 (l + b)
where: l is the length = 12 units and b is the breadth = 8 units. So that:
Perimeter of KMPT = 2 (12 + 8)
= 40 units
Dilating KMPT by a scale factor of
would create K'M'P'T' of dimensions;
× 12 units by
× 8 units. Thus, the dimensions of K'M'P'T' would be 9 units by 6 units.
Perimeter of K'M'P'T' = 2 (l + b)
= 2(9 + 6)
= 30 units
Comparing the perimeters of KMPT and K'M'P'T', the perimeter of K'M'P'T' would be
× perimeter of KMPT.
Therefore, if the perimeter of KMPT is x units, then;
perimeter of K'M'P'T' =
* x units
=
x units
I really need points sorryyyyyyyy
Answer:
1) 2
2) -2
Step-by-step explanation:
1)
x - 5 = -3
Add 5 to both sides
x = 2
2)
3 - 2x = x + 9
Add 2x to both sides.
3 = 3x + 9
Subtract 9 from both sides
-6 = 3x
Divide both sides by 3
-2 = x
x = -2
Hope this helps you understand! :D
