Answer:
20 m by 10 m
Step-by-step explanation:
let w be width and l be length , then
2(l + w) = 60 ( divide both sides by 2 )
l + w = 30 ( subtract w from both sides )
l = 30 - w → (1)
lw = 200 → (2)
Substitute l = 30 - w into (2)
w(30 - w) = 200 ← distribute parenthesis on left side
30w - w² = 200 ( subtract 200 from both sides )
30w - w² - 200 = 0 ( multiply through by - 1 )
w² - 30w + 200 = 0 ← in standard form
(w - 10)(w - 20) = 0 ← in factored form
Equate each factor to zero and solve for w
w - 10 = 0 ⇒ w = 10
w - 20 = 0 ⇒ w = 20
Substitute these values into (1)
l = 30 - 10 = 20
l = 30 - 20 = 10
dimensions of field is 20 m by 10 m
Answer:4(2x + 1) = 12x + 3 - 4x +1=0
Step-by-step explanation:
group like terms =4(2x+1)=12x-4x+3+1
add similar elements=4(2x+1)=8x+3+1
add the numbers=4(2x+1)=8x+4
expand=8x+4=8x+4
subtract 4 from both sides 8x+4-4=8x+4-4
simplify=8x=8x
subtract 8x both sides=0
Remember
(ab)/c=a(b/c)
and
b/b=1 when b=b

Answer:
Y=3x-1
Step-by-step explanation:
Let x =1 then ,Y=(3×1)-1=2
Let x=2 then, Y=(3×2)-1=5
Let x=3 then Y=(3×3)-1=8
Let x=0 then Y=(3×0)-1=-1
