Answer:
The length of each of the 4 sides of a square is the same. Then
5x - 8 = 3x
2x = 8
x = 4
5(4) - 8 = 12
3(4) = 12
The length of each side is
L = 4.
The perimeter is 4 times the length.
P = 4L = 4(4) = 16
Step-by-step explanation:
Answer:
15 cm, 15 cm, 11 cm
Step-by-step explanation:
let the equal sides be x then the third side is x - 4
The perimeter is the sum of the 3 sides and is 41 cm , then
x + x + x - 4 = 41
3x - 4 = 41 ( add 4 to both sides )
3x = 45 ( divide both sides by 3 )
x = 15
x - 4 = 15 - 4 = 11
The sides are 15 cm, 15 cm, 11 cm
Answer:
120
Step-by-step explanation:
Answer:
-62
Step-by-step explanation:
using bodmas (brackets,other,division, multiplication, addition and subtraction)
starting with brackets(6-68+9)
68+9 because adding comes before subtracting is 77
now 6-77 is -71
now multiplication 1-2(-71)
which is -1(-71) which is 71
now the 9 - 71 which is -62
