The best estimate for the diagonal of the rectangle is 3 ⇒ B
Step-by-step explanation:
In a rectangle:
- The length and the width are perpendicular
- The length of its diagonal =
(the diagonal is the hypotenuse of a right triangle whose legs are the length and the width of the rectangle)
∵ The width of a rectangle = x
∵ The length of the rectangle = 2x
∵ The diagonal =
- Substitute the length by 2x and the width by x
∴ The diagonal =
∴ The diagonal =
∴ The diagonal =
∵ x = 1.33
- Substitute the value of x by 1.33 to find the diagonal
∴ The diagonal =
∴ The diagonal = 2.973
∴ The diagonal ≅ 3

<h2>Answer:</h2>
11 and 15
<h2>Explanations:</h2>
Given the arithmetic sequence -1, 3, 7 __, __, you are to find the next two terms of the sequence.
The nth term of an arithmetic sequence is given as;
where:
• a is the ,first term
,• n is the ,number of terms
,• d is the ,common difference
From the given sequence;
a = -1
d = 3 - (-1) = 7 - 3 = 4
For the fourth term, n = 4;
For the fifth term, n = 5;
Therefore the next two terms of the arithmetic sequence are 11 and 15.
