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
Answer:
r = 46
Step-by-step explanation:
To solve the equation, solve for r by isolating the variable. Whatever you do to one side, do to the other.
1) First, simplify the right side by combining like terms. Subtract the coefficients of the terms with the same variables. Subtract 5r by 4r.
2) Now, finally isolate r by subtracting both sides by 14.

So, r = 46.
Answer:
1/12
Step-by-step explanation:
there is 1/2 chance of flipping heads and 1/6 chance of rolling a six
1/2*1/6=1/12
