Answer:
length=11 width=10
Step-by-step explanation:
Create two equations with length(l) and breath(w) as our unknowns
2l+2w=42
2l=42-2w
2l/2=(42-2w)/2
l=21-w(equation 1)
lxw=110
lw=110
Substitute equation one into equation two
(21-w)w=110
21w-w²=110
Write your equations in standard quadratic form
0=w²-21w+110
solve this as a quadriatic tri nominal
0=(w-10)(w-11)
0=w-10. or 0=w-11
10=W. 11=L
The correct answer is this one: "B) More girls than boys prefer Dodge over Ford or Chevrolet." Jamie collected data from her classmates on their favorite make of car. Based on the data collected, if one hundred boys and one hundred girls are given their choice of a car then <span>More girls than boys prefer Dodge over Ford or Chevrolet.</span>
Treat each side as if it's their own equation.
14-2*2
First multiply
14-4
Now subtract
10/5
Now divide
2
2 is the answer
