Answer:
1400m^2
Step-by-step explanation:
Solution,
Let the breadth of the rectangle be x m, then the length of the rectangle will be x+5 m,
Now,
Perimeter of the rectangle=2(l+b)
150=2(x+5+x)
150=2(2x+5)
150=4x+10
150-10=4x
140=4x
140/4=x
35=x
So, the breadth of the rectangle=35 m
and length=(35+5)m=40m
Again,
Area of the rectangle=l×b
=40m×35m
=1400 m^2

Answer:
B. 10
Step-by-step explanation:
To find the answer we would plug each given number into x to see if it makes the equation true
<em>A. 2(5) = 20 </em>
<em> 10 </em>
<em> 20</em>
<em>B. 2(10) = 20</em>
<em> 20 = 20</em>
<em>C. 2(20) = 20</em>
<em> 40 </em><em>20</em>
As you can see, the only answer that makes the equation 2x=20 true, is answer B
<span>So before we can participate in our Chem labs, we need to answer questions regarding the experiment. I'm not the best at Chemistry and I'm having some trouble with this one problem.
Here's the experiment's instructions (Part A)
And the problem, "When performing today’s experiment, your lab partner decides to add all the reagents into one beaker instead of two separate beakers. After adding everything together and waiting a significant amount of time, you see no reaction occur. What was the problem?"
Could it be that all of the separate beakers form different mixtures and just adding everything together at once doesn't allow that to happen? I have honestly have no clue, any help is appreciated</span>
Answer:
(5 , 3)
Step-by-step explanation:
The midpoint = (3+7)/2 , (9-3)/ 2
= 10/2, 6/2
= (5 , 3)
