Answer: 4x2 + 32x − 80 = 0
Step-by-step explanation:
Area of a rectangle is given by
A = l*w
The length is (2x+10) and the width is (2x+6)
A = (2x+10)(2x+6)
FOIL
first 2x*2x = 4x^2
outer 2x*6 =12x
inner 2x*10 =20x
last 10*6=60
Add this together
4x^2 +12x+20x +60 = 4x^2 +32x+60
This must equal 140 inches
4x^2 +32x+60 = 140
Subtract 140 from each side
4x^2 +32x+60-140 = 140-140
4x^2 +32x -80=0
An addition sign between 978 and 842 would make the equation true!
Answer:
Step-by-step explanation:
Perimeter = 2*(length +width)
P = 2*( x+8 + y-1)
P = 2*(x + y + 7)
P =2x + 2y + 17
The correct answer is trinomial it has three terms
