The answer is D you are multiplying the hours, days, weeks, and months, hopes this helps (:
Answer:
A
Step-by-step explanation:
Fill in the x and y into the equation you provided, A is the only one that is true
Well if 1.5 m is covered in 1 second, the distance would be calculated as d=1.5t.
3x + 11x = 84
add 3x and 11 x
14x = 84
Take 14 to other side and divide it
x = 6 answer
1) width = x
length = x + 8
perimeter = 2 (length + width)
196 = 2 * (x+8+x)
196 = 2* (2x+8)
196 = 4x + 16
180 = 4x
x = 45 (thats width)
2) length would be 45+8=53
3) area = length times width = 45 * 53 = 2385 square feet
