L + W + L + W = 1,008 feet
A) 2L + 2W = 1,008 feet
B) L = W + 166
Multiplying Equation B by -2
B) -2L = -2W -332
B) -2L + 2W = -332 then adding equation A
A) 2L + 2W = 1,008 feet
4W = 676
Width = 169
Length = 169 + 166 = 335
Answer:
5×2is your answer right answer
Answer:
3
Step-by-step explanation:
18*x=54 (divide both sides by 18)
x = 54 ÷ 18
x = 3
Answer:
AC = √105 ≈ 10 cm (nearest whole number)
Step-by-step explanation:
Use Pythagoras' Theorem: a² + b² = c²
(where a and b are the legs, and c is the hypotenuse of a right triangle)
Give one of the legs = 4cm and the hypotenuse = 11 cm:
⇒ 4² + AC² = 11²
⇒ 16 + AC² = 121
⇒ AC² = 121 - 16
⇒ AC² = 105
⇒ AC = ±√105
As distance is positive, length of AC = √105 ≈ 10 cm (nearest whole number)
