Answer:
Its n = 45
Step-by-step explanation:
Multiply both sides of the equation by 3 .
3 ⋅
= 3 ⋅ 14
Simplify both sides of the equation.
n = 45
I hope this helps

Answer: -4x+2y=12
Step-by-step explanation:All you have to do is multiply the variables one after the other taking note of the sign
length = 4 yards and width = 3.5 yards
let width be w then length is 2w - 3
area = w(2w - 3) = 14 (rearrange in standard form )
2w² - 3w - 14 = 0 ← in standard form
(2w - 7 )(w + 2 ) = 0 ← in factored form
equate each factor to zero and solve for w
2w - 7 = 0 ⇒ w = 3.5
w + 2 = 0 ⇒ w = - 2
but w > 0, hence w = 3.5
width = 3.5 yards and length = (2 × 3.5 ) - 3 = 4 yards
