For the segment DE to be the midsegment of the triangle ABC, the point D must cut AB in two equal halves, and point E must cut AC in two equal halves as well, that way, DE touches both ends right in the middle
and that can only occur if AD is 4 (half of 8) and AE is 3 ( half of 6)
Answer:
Step-by-step explanation:
Area of semi-circle is
≈
× 4² ÷ 2 ≈ 25 cm²
Area of square is 8² = 64 cm²
Total area is 25 + 64 = 89 cm²
Answer:
P = 10x + 4
Step-by-step explanation:
Formula to find perimeter:
P = 2(l + w)
P = 2(2x + 3x + 2)
P = 2(5x + 2)
P = 10x + 4
Option a
- Option be is seeming to be irrational but its not
How?


Hence correct option is a
Let's think about what happens when you find the price after tax. Let the price before tax be

. The tax rate is

, so the tax part of the total price is

. Adding that onto the original price, we see that


So, we can just divide each side by

to get the original price, which rounded to two decimal places is

.
