Answer:
The quadratic function representing the total area of the park and the path is
Step-by-step explanation:
The width of the rectangle is x----------(1)
Then the length = twice it's width
Length =
Length = 2x------------------(2)
Now the width along with the foot path = x +3+3 = x+9
the length along with the foot path = 2x + 3+3 = 2x +9
The total area of the park and the path =
that is
=> (2x + 9)(x+9)
=>
=>
Answer:
-4,-5
Step-by-step explanation:
first set the equation equal to 0, v^2+9v+20, factor v^2+4v+5v+20, v(v+4) 5(v+4), so the 2 factors are (v+5) and (v+4), set both equal to that 0. v+5=0 v=-5 and v+4=0 v=-4, so the answer is -4 and -5
X=number of boys.
y=number of girls.
we suggest this system of equation
x/y=9/7
x=y+116
We solve this system of equation by substitution method.
(y+116)/y=9/7
7(y+116)=9y
7y+812=9y
9y-7y=812
2y=812
y=812/2=406
x=y+116
x=406+116=522
answer: At the school there are 522 boys and 406 girls.
to chek.
522/406=1.2857...
9/7=1.2857...
The number of boys (522) is equal to 406+116=522.
