Answer: The Length of the rectangle is 18 feet.
The width is 8 feet
Step-by-step explanation: Perimeter is 2w + 2L
Length here is <u>2w + 2</u> Substitute this value for L in the equation.
P = 2w + 2L
52 = 2w + 2(2w + 2) distribute and add
52 = 2w + 4w + 4
52 = 6w + 4 Subtract 4 from both sides, Then divide both sides by 6 to solve for w
48 = 6w
8 = w <u>The width is 8 ft</u>
Substitute into the original expression for Length
Length here is <u>2w + 2</u> : 2(8) + 2 16 + 2 = 18
<u>The Length is 18 feet.</u>
<u>Check:</u> in the original equation P = 2w + 2L
52 = 2(8) + 2(18)
52 = 16 + 36 TRUE!
Answer:
A₍ₙ₎ = - 74 + (n-1) x 6
Step-by-step explanation:
A₍ₙ₎ = A₍₁₎ + (n-1) x d
A₍₁₈₎ = 28 = A₍₁₎ + 17 x d ..... (1)
A₍₄₀₎ = 160 = A₍₁₎ + 39 x d .....(2)
(2)-(1) 132 = 22d
d = 6
A₍₁₎ = 28 - 17 x 6 = -74
formula: A₍ₙ₎ = - 74 + (n-1) x 6
