Answer:
<h2><u><em>8 feet</em></u></h2>
Step-by-step explanation:
<u><em>Given,</em></u>
Perimeter of a rectangular pool (P) = 40 feet
Length of the pool (l) = 12 feet
<u><em>Let,</em></u>
Width of the pool be = w
<u><em>As we know,</em></u>
- <em>Perimeter of a rectangle = 2(length + width)</em>
<u><em>Therefore,</em></u>
<em>By the problem,</em>
=> 2(l + w) = P
- <em>[On substituting the values of l = 12 and P = 40]</em>
=> 2(12 + w) = 40
- <em>[On multiplying 2 with 12 and w]</em>
=> 24 + 2w = 40
- <em>[On subtracting both sides with 24]</em>
=> 24 - 24 + 2w = 40 - 24
- <em>[On Simplifying]</em>
=> 2w = 16
- <em>[On Dividing both sides with 2]</em>
=>
= 
- <em>[On Simplifying]</em>
=> w = 8
<u><em>Hence,</em></u>
<u><em>The required width of the pool is 8 feet. (Ans)</em></u>
Answer:
Step-by-step explanation:
AB and DC are parallel, so ∠B and ∠C are supplementary angles.
∠B = 180°-∠C = 79°
AD and BC are congruent. ∠A = ∠B = 79°
Answer:
5(x-2)
Step-by-step explanation:
hereeeeee it is for the answer
Assuming you want us to simplify
remember
negative times negative=positive
and
remember the distributive proeprty
a(b+c)=ab+ac
and
-a(b+c)=-ab-ac
oh, and order of operations
so
-4(4/3v-4)-3(1/2v-4)
distribute
-4(-4/3v-4)=-4(-4/3v)-4(-4)=16/3v+16
-3(1/2v-4)=-3(1/2v)-3(-4)=-3/2v+12
so we now gots
16/3v+16-3/2v+12
group like terms
16/3v-3/2v+16+12
combine like terms
first the v terms
16/3v-3/2v=32/6v-9/6v=23/6v
then the constants
16+12=28
so we gets
23/6v+28 is the simlified form
