Step-by-step explanations:
Expression for perimeter is 2(14-x + x) = 28
<u>Step-by-step explanation:</u>
Step 1:
Given expression for area of the rectangle = a(x) = x(14-x) where x is the width. Then length = 14-x since area = length × width
Step 2:
Find expression for perimeter of the rectangle.
Perimeter of the rectangle = 2(length + width) = 2(14 - x + x) = 2 × 14 = 28
Answer:
No solution
Step-by-step explanation:
Apply the distributive property:
-2x - 2 = -2x + 5
Add 2x to each side:
-2 = 5
Since negative two never equals five, there is no solution to this equation.
Maybe it’s -2(46+13) or -92-26v
The third term, fourth term and tenth term are -1, -3, -15 respectively.

What is a sequence?</h3>
A sequence is a pattern of numbers in which successive terms differ by an constant term called the common difference or ratio.
Analysis:
For a sequence defined by the rule A(n) = 3 + (n-1)(-2)
Third term, n = 3
A(3) = 3 + (3-1)(-2) = -1
Fourth term, n = 4
A(4) = 3 + (4-1)(-2) = -3
Tenth term, n = 10
A(10) = 3 + (10-1)(-2) = -15
In conclusion, the third, fourth, tenth terms are -1, -3 and -15 respectively.
