Answer:
119 square centimeters.
Step-by-step explanation:
Write the problem as an equation.
2(2x+3)+2x=48
Where x is width of the rectangle. 2x+3 represents the length.
4x+6+2x=48
6x+6=48
6x=42
x=7
The width is 7 cm. Then, find the length.
(2x+3) Given
(2)(7)+3 Plug in 7 for x
14+3
17
Then, find the area, width*length
17*7=119

Answer:
Last option, a translation of 1.5 units left, 0.5 unit up, then a reflection across the x-axis
Step-by-step explanation:
Let's pick any random point. So let's just chose point L. Comparing point L to point L', we can already see that the options given are incorrect. For example, the first option with just translations is incorrect because when we do translate point L 1.5 units left and then 1.5 units down, it does not line up with point L'. For the second and third options, we know that L(-2.5, 1.5) and L'(-4,-2). Therefore, there must be some sort of shift left, right, up, or down, to go from coordinates with decimals to coordinates with whole numbers, leaving the last option, D, as the correct one.
