Answer:
12 cm
Step-by-step explanation:
width = x
length = x + 5
perimeter = 38cm
perimeter = length + width + length + width
x + 5 + x + x + 5 + x = 38
4x + 10 = 38
4x = 28
x = 7
length = x + 5 = 7 + 5 = 12
Answer:
x = 7, x = 5
Step-by-step explanation:
Given 2 intersecting chords, then
The product of the parts of one chord is equal to the product of the parts of the other chord.
(1)
27x = 9 × 21 = 189 ( divide both sides by 27 )
x = 7
(2)
12(3x - 5) = 120 ( divide both sides by 12 )
3x - 5 = 10 ( add 5 to both sides )
3x = 15 ( divide both sides by 3 )
x = 5
