Answer :And fart begins
Step-by-step explanation:
The breadth of rectangle is 14 cm
The perimeter of rectangle is 65 cm
<em><u>Solution:</u></em>
Given that,
Area of rectangle = 259 square centimeter
Length of rectangle = 18.5 cm
<em><u>The area of rectangle is given by formula:</u></em>

<h3><u>Find the breadth:</u></h3>
Substitute the given values in above formula:

Thus breadth is 14 cm
<h3><u>Find the perimeter:</u></h3>
The perimeter of rectangle is given by formula:

Substitute the given values in above formula:

Thus perimeter of rectangle is 65 cm
Answer:
C
Step-by-step explanation:
Let's simplify this expression first:

- In Line 2, we have used distributive property (
) and thus multiplication. - In Line 3, we have combined like terms
<em>Choices A, B, and D can be eliminated as we have done those to simplify the expression.</em>
Thus, "evaluation" -- choice C is the correct answer for this question.
<u>Evaluation</u><u> is when we plug in a specific value in the variables to find a "value/answer" of the expression given.</u>
Answer:
No
Step-by-step explanation:
$3.98 + $2.75 + $ 3.87 ≠ $10
$3.98 + $2.75 + $ 3.87 = $10.60
Answer:
The first side= 9 inches
The second side=12 inches
The third side=7 inches
Step-by-step explanation:
Lets make expressions to represent each of the three sides of the triangle.
If we start with the second side and say its length is x inches, then the first side becomes (x-3) inches.
The third side is gotten by subtracting 2 inches from this first side. Then its expression becomes: (x-3)-2 which can be simplified to x-5 inches.
The perimeter of a triangle is found by adding the lengths of the three sides of the triangle, thus, we add the three expressions and then equate the result to the numerical value of the perimeter.
x+(x-3)+x-5=28
3x-8=28
collecting like terms together we get:
3x=36
x=12 inches
Therefore, the first side (x-3) we substitute for x so 12-3=9
second side x is 12
the third side x-5 gives 12-5=7
