Answer:

Step-by-step explanation:
We are given that the equation of lines


According to question
The vector perpendicular to the lines is given by
and 
Therefore, the angle between two vectors is given by

Using the formula




Hence, the acute angle between the lines is given by

Let <em>n</em> be the smallest of the three numbers. Then
<em>n</em> + (<em>n</em> + 1) + (<em>n</em> + 2) = 5 ((<em>n</em> + 1) - 22)
Solve for <em>n</em> :
3<em>n</em> + 3 = 5 (<em>n</em> - 21)
3<em>n</em> + 3 = 5<em>n</em> - 105
2<em>n</em> = 108
<em>n</em> = 54
Then the three numbers are 54, 55, and 56.
(p>64) divided by 4 is less than or equal to w

Answer is

When it's powered numbers, remember to choose the one with the largest power. For example,

And

Choose 10, same goes to y, where you choose 7 not 4 since 7 is larger.

Answer:
approx 31.24 euro
Step-by-step explanation:
area of vickys wall =5.7 × 2.8=15.96
area covered by one wallpaper=0.53×12=6.36
no of wall paper required=area of wall/area of 1 wall paper
=15.96÷6.36=2.50943396226
cost of 1 wall paper=12.45
cost of 2.50943396226 wall paper=31.2424528302 euro
