Answer:
102
Step-by-step explanation:
Each triangle will have a perimeter of 3. When joined, the outside triangles will have 2 sides showing, or 2 inches. The middle 98 will only have one free side, or one inch. This means that 98*1 + 2*2 = 102
Answer:
5 pounds / Make sure to read the explanation so you know how to solve it

Answer:
x + 4 - 3√2 and x + 4 + 3√2
Step-by-step explanation:
When other methods seem to difficult to apply, try using the quadratic formula:
Here a = 1/2, b = 4 and c = -1.
Then the "discriminant" is b^2 - 4ac, or
(4)^2 - 4(1/2)(-1), or 16 + 2 = 18
Then the roots are:
-4 ± √18, or -4 ± 3√2
and thus the factors are x + 4 - 3√2 and x + 4 + 3√2
x = ---------------------
Answer:
length=4 meters. width= 40 meters.
Step-by-step explanation:
88-4*2=80. 80 divided by 2 is 40. So, the width os 40 meters and the length is 4 meters.
Because irrational numbers are unpredictable. for example, you can write 0.25 in a fraction (1/4) because 1/4 is 1 divided by 4 which is 0.25. But you can never divide 2 numbers to get a decimal that never ends
