12x - 13 - x - 9 + 10x
First, get the like terms together
12x + 10x - x -13 -9
Now, combine like terms
12x + 10x - x = 21x
-13 - 9 = -22
Final Answer:
21x - 22
P = 2(L + W)
P = 68.4
L = 4W + 9.7
68.4 = 2(4W + 9.7 + W)
68.4 = 2(5W + 9.7)
68.4 = 10W + 19.4
68.4 - 19.4 = 10W
49 = 10W
49/10 = W
4.9 = W <==== the width is 4.9 cm
L = 4W + 9.7
L = 4(4.9) + 9.7
L = 19.6 + 9.7
L = 29.3 <=== the length is 29.3 cm
Letter C because it is being reflected over the x axis and having a translation through the horizontal line
15 I believe is the answer you are looking for.
Answer:
8. the length is 88/5cm or 17.6cm
Step-by-step explanation:
8.perimeter =2L + 2W
when you convert the width 42/5 = 8.4
so 52 = 2L + 2*8.4
52= 2L + 16.8
52 - 16.8 = 2L
35.2 = 2L
divide both sides by 2
L = 17.6cm
