That's a quadratic equation in

, which means we get an extra square root and

at the end.

We factor,


Answer:
Part A.
w = √(d^2 - l^2)
Part B.
w = 6ft
Step-by-step explanation:
length l = 8ft
diagonal d = 10ft
width w = ?
we can see it as a Trangle, so using a Pythagorean theorem,
d^2 = l^2 + w^2
w = √ (d^2 - l^2)
w = √ (10^2 - 8^2)
w = √ (100 - 64)
w = √ 36
w = 6
Answer:
y < - 6
Step-by-step explanation:
Given
- 2y > 12
Divide both sides by - 2, reversing the symbol as a result of dividing by a negative quantity.
y < - 6
Since the congruent operator is ≅ and since AD is congruent to BD, I'm going to assume that you want to prove that AD is congruent to BD.
1. DE is equal to CD by definition since D is the midpoint of CE.
2. AE is equal to BC since opposite sides of a rectangle are equal to each other.
3. Angle AEC is equal to Angle BCE since all angles in a rectangle are right angles and all right angles are equal to each other.
4. Triangles ADE and BDC are congruent to each other because we have SAS congruence for both triangles.
5. AD is congruent to BC since they're corresponding sides of congruent triangles.
