The perimeter is just adding all the sides together.
a.) 180 = 40 + 40 + x + x
180 = 80 + 2x Subtract 80 on both sides
100 = 2x Take 1/2 of 100 to get x
x= 50cm
b.) 1000 = 150 + 150 + x + x
1000 = 300 + 2x Subtract 300 on both sides
700 = 2x Take 1/2 of 700 to get x
x = 350
In point slope form: y - 6 = 5(x - 1)
1 in 7
Step-by-step explanation:
Your one-digit choices: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
But they're nonzero, so: 1, 2, 3, 4, 5, 6, 7, 8, 9.
But they can't be repeated and 9 and 8 are used, so: 1, 2, 3, 4, 5, 6, 7.
Only 7 numbers left, so chances are, 1 in 7.
