Your answer is A) 34.
A rectangle has four sides as you know.
If you use 34 as your width, both sides for width would total 68.
Then, same steps as before, accounting for both length sides by multiplying 68 by 2 and get you’d get 136.
68 (both width sides) + 136 (both length sides) would get your total of 204.
Answer:
2x+y=15x+y=10
Consider the first equation. Subtract 15x from both sides.
2x+y−15x=y
Combine 2x and −15x to get −13x.
−13x+y=y
Subtract y from both sides.
−13x+y−y=0
Combine y and −y to get 0.
−13x=0
Divide both sides by −13. Zero divided by any non-zero number gives zero.
x=0
Consider the second equation. Insert the known values of variables into the equation.
15×0+y=10
Multiply 15 and 0 to get 0.
0+y=10
Anything plus zero gives itself.
Answer:
18 seconds
Step-by-step explanation:
convert km/h to m/s and you get 22.22m/s. Then divide 400 by 22.22 and the answer is 18 seconds.

First of all, we know that the man's age was divisible by 8 one year ago. So, let's list a few numbers that are divisible by 8, and work from there.
8, 16, 24, 32, 40, 48, 56, 72, 80, 88, 96 are all divisible by 8.
We also know that his current age is the square of his son's age. So we can check the numbers that follow the multiples of eight to see if they'll work.
The subsequent numbers, in order, are
9, 17, 25, 33, 41, 49, 57, 73, 81, 89, 97
Now, let's list which ones are squares, meaning a number multiplied by itself is equal to anther number.
9 is the square of 3
25 is the square of 5
49 is the square of 7
81 is the square of 9
Only these four will work, but right now, ANY of these four will work. Let's use a little science to narrow it down.
It is scientifically improbable for a 9-year-old to have a 3-year-old son, so we'll rule that one out. It's also highly unlikely that an 81-year-old has a 9-year-old son, so we'll cross that off the list, as well.
This leaves a 25-year-old man with a 5-year-old son, and a 49-year-old man with a 7-year-old son, both of which are most likely.
At this point, you can choose whichever you'd like, or put down both as the answer.
The man and his son's present ages are either 25 and 5, or 49 and 7.
