When it says how many more that means to subtract and that will be 20
All the answers, which are reduced to lowest terms, and the steps are in the images below (they’re in order based on the questions). I only answered questions <em>a</em> through <em>e </em>(not f), because it would only allow me to attach five photos. The answer for question <em>c</em> is in mixed numbers form because image said , so as an improper fraction it’s .
Hope this helps my friend! :)
Imagine a 'U' shape
sides are x legnth
base is b legnth
2x+b=25
area is height times base=xb
xb=50
2x+b=25
solve
minus 2x both sides
b=25-2x
sub for b
x(25-2x)=50
25x-2x^2=50
times -1 both sides
2x^2-25x=-50
add 50 both sides
2x^2-25x+50=0
use quadratic formula or something
x=2.5 or 10
A is the answer
