If two sides of a rectangle add up to 18cm and the area is 80 units squared then the length is 10cm, and the width is 8cm. If you add 10 and 8 together you get 18, and if you multiply those you get 80 units squared. Hope this helps!
Answer:
r=-7/17
Step-by-step explanation:
6r-7=23r=
We move all terms to the left:
6r-7-(23r)=0
We add all the numbers together, and all the variables
-17r-7=0
We move all terms containing r to the left, all other terms to the right
-17r=7
r=7/-17
r=-7/17
Answer:
<u><em>the equation is true</em></u>
Step-by-step explanation:
solve the equation 4x + 6 = 4 + 2(2x + 1). Which choice describes the meaning of his result, 6 = 6?
4x + 6 = 4 + 2(2x + 1)
4x + 6 = 4 + 4x + 2
6 = 4 + 2
<u><em>6 = 6</em></u>
<h2><u><em>
the equation is true</em></u></h2>
You can factor it by taking out the five, since it is a common factor of 5 and 15 (for example: 5(-x - 3) ), you can remove the negative value ( -1(5x+15) ), or your can remove the negative and the 5 (-5(x+3) ).
