Solutions
We know that a rectangle has four sides and the perimeter of a rectangle is the distance around the outside of the rectangle.The opposite sides of a rectangle are congruent To find the perimeter you have to use the formula 2 × <span>(Side A + Side B).
</span>
We have the side lengths 7.7 mm and 17.2 mm.
Solve
2 × <span>(Side A + Side B)
2 </span>× <span>( Side A (7.7) + Side B (17.2) )
</span>= (7.7 x 2) + (17.2 x 2)
= 49.6
<span>The perimeter is 49.6 mm². </span>
Answer:
The numbers are 12 and 3.
Step-by-step explanation:
We can solve this problem by working with the information we have and setting up some equations.
We know that one number is four times as large as another. So, let the smaller number be represented by the variable x and the bigger number be represented by 4x, since it is four times as large.
Now, we know that if the numbers are added together, then the result is six less than seven times the smaller number. This can also be represented by the equation 4x + x = 7x - 6.
Let's solve that equation like so:
So, the smaller number must be 3 (remember that x represented the smaller number). To find the bigger number, all we need to do is multiply 3 by 4, which gives us 12. Therefore, the numbers are 12 and 3.
First find the slope of the line = (y2 - y1) / (x2 - x1) where the 2 points are (x1, y1 and (x2, t2).
Then substitute the values of the slope (m) and one of the points into the point-slope formula
y - y1 = m(x - x1)
Answer:Irrational
Step-by-step explanation: There is not a number you can square to get 23. The answer would be a repeating number, being irrational.
