Answer:
what is the question
Step-by-step explanation:
From the description, you can get two equation that looks like this:
L= 2*W+6.7cm
Perimeter= 57.2cm
Using perimeter formula, you can put the first and second equation like this:
perimeter= 2L + 2W
57.2cm= 2(2*W+ 6.7)+2W
57.2cm= 4W+ 13.4+ 2W
57.2- 13.4= 6W
W= 43.8/6= 7.3 cm
L= 2W+ 6.7
L= 2*7.3 + 6.7= 21.3
Answer: <span>A. Length=21.3 cm; width=7.3 cm</span>
X=5.
Explanation:
Take 3x+1=5x-9 and subtract 1 from both sides.
Now you have 3x=5x-10, Subtract 5x from both sides to get -2x= -10
Now divide both sides by -2 and you have x=5 :).
