Answer:
D). 290 feet
Step-by-step explanation:
Length of the yard = 65 feet
Width of the yard = 80feet
The Perimeter of the yard = 2(l + b)
= 2 * (65 + 80)
= 2 * 145
= 290 feet
∵ Fencing required = 290 feet
Thus, <u>option A</u> is the correct answer.
Is known that
(a + b)² = a² + 2.a.b + b²
So:
(x + 4)² = x² + 2.x.4 + 4² = x² + 8x + 16
Yes because you are simply translating the shape and moving it and not changing the shape.
Hello from MrBillDoesMath!
Answer:
3
Discussion:
34 + 2x = 40 => subtract 34 from both sides
(34-34) + 2x = 40 - 34 => as (34-34) = 0 and 40-34 = 6
2x = 6 => divide both sides by 2
x = 6/2 = 3
Check the answer:
Does 34 + 2x = 40 if x = 3 ?
Does 34 + 2(3) = 40 ?
Does 34 + 6 = 40 ? YES! so the answer checks.
Thank you,
MrB
