Answer: 20 feet by 20 feet.
Step-by-step explanation:
1. You know that 
is the original measure of one side. Since it is a square, all its sides are equal.
2. Therefore, to solve the problem you only need to solve for , as you can see below:
- You have that:
- Then, you obtain the following quadratic equation:
- Apply the Quadratic formula to solve it:
- Then, you obtain:
3. The dimensions cannot be negative, therefore, the answer is: 20 feet by 20 feet.
Answer:
b.y=4
c. x=6
These are the answers hope this helps
Simple, what you're basically doing is simplifying,
well, you have 3x and you have
12/3=4
and you can "cancel" out an x, making your answer,
.
M+f=35
f=5+m^2
sub 5+m^2 for f
m+5+m^2=35
m^2+m+5=35
minus 35 both sides
m^2+m-30=0
factor
what 2 numbers mulitply to get -30 and add to get 1
-5 and 6
(m-5)(m+6)=0
set to zto
m-5=0
m=5
m+6=0
m=-6
age can't be negative
max is 5
father is 30
