Answer:
If the expression is 
, then the answer is the first option.
If the expression is 
, then the answer is the third option.
Step-by-step explanation:
Remember that when you have a radical expression in the form ![\sqrt[n]{x}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bx%7D)
, you can rewrite as:
Then:
- If the expression is , then you can rewrite it in the following radical form:
![=4\sqrt[7]{x^3}](https://tex.z-dn.net/?f=%3D4%5Csqrt%5B7%5D%7Bx%5E3%7D)
(This form matches with the first option.)
- If the expression is , then you can rewrite it in the following radical form:
![=\sqrt[7]{(4x)^3}](https://tex.z-dn.net/?f=%3D%5Csqrt%5B7%5D%7B%284x%29%5E3%7D)
(This form matches with the third option).
Answer:
The second one is the best answer to your question

1. BC/CD = AC/CE 1. Given
2. <BCA is congruent to <ECD 2. Vertical angles are congruent
3. Tr.ACB is congr to Tr.ECD 3. SAS Similarity
Well the area of a trapezoid is defined by the following formula:
A =
where b₁ and b₂ are the bases of the trapezoid and h is the height of the trapezoid.
Let's plug in what we know into this formula:
h = 7 the perpendicular distance between the two bases
b₁ = 15 the shorter parallel side
b₂ = 25 the longer parallel side made up of 4 + 15 + 6
so, A =
This is in square units of measure of course, so 140 in²
