5:2 means 5 to 2 Here is an example:
5 spoons of red paint are put in the bucket for every 2 spoons of white paint. You can do ratios in fraction form, word form, or ratio form.
<span>Answer: 4*x+3=5+x
Explanation: four times a number means 4*x plus three means 4*x+3 is the same as which means = five plus the number which is 5+x </span>
these are the answers ( i just did this and got it right)
1) Ionic radii tend to increase down a group.
4) Cationic radii tend to decrease across a period.
5) Ionic radii increase when switching from cations to anions in a period.
There are no numbers with an A between 1-100
Answer:
Lets take all factors into consideration first
The door is a rectangle and the area of a rectangle is length times width
Let the width be w
Let the length be l
Equation length × breadth = area
(w+48)w = 3024
w^2 + 48w = 3024
w^2 + 48w - 3024 = 0
w^2 + 84w - 36w - 3024 = 0
w(w + 84) -36 ( w + 84) = 0
(w + 84) (w - 36) = 0
w + 84 = 0 AND w - 36 =0
w = -84 and w = 36
Since width cannot be negative, the right answer is 36
How did I get 84 and 36? Well, I had to factorize 3024 and since 84 times 36 is 3024 and 84 minus 36 is 48, I chose them.
