Answer:
it's 68 if that equation is equals to 0.
Step-by-step explanation:
136 - 2a = 0
=> 136 = 2a
=> 136/ 2 = a
=> a = 68.
The <em>approximate surface</em> areas of corresponding prisms are listed below:
- <em>A = 108 units²</em>
- <em>A = 229 units²</em>
- <em>A = 454 units²</em>
<h3>How to match given surface areas with given figures</h3>
The <em>surface</em> area of the each figure (), in square units, is equal to the sum of the <em>surface</em> area of the two bases (), in square units, and the <em>surface</em> areas of the <em>lateral</em> sides (), in square units. Since bases are <em>regular</em> polygons, <em>base surface</em> area can be determined by this expression:
(1)
Where:
- <em>l</em> - Side length, in units
- <em>n</em> - Number of sides
The area of one lateral side is expressed by this expression:
(2)
Where <em>h</em> is the height of the rectangle, in units.
The total surface area is defined by the following formula:
(3)
Now we proceed to calculate each surface area:
<h3>Case I (
,
,
)</h3>
<em>A = 108.136 units²</em>
<h3>Case II (
,
,
)</h3>
<em>A = 228.631 units²</em>
<h3>Case III (
,
,
)</h3>
<em>A = 453.874 units²</em>
The <em>approximate surface</em> areas of corresponding prisms are listed below:
- <em>A = 108 units²</em>
- <em>A = 229 units²</em>
- <em>A = 454 units²</em>

Her answer represents "-3.7 less than 4 times a number is 11.9". The correct equation should be -3.7n-4=-11.9.
Answer:
1,425,600
Step-by-step explanation:
because 1miles equal 5280ft so you need use 4.5 time the 5280 and time60 because 1hour equal 60min
Answer with explanation:
- Monomial = Polynomial with one term.
- Binomial = Polynomial with two terms.
- Trinomial = Polynomial with three terms.
- Degree - highest power of variable
- Leading coefficient - Coefficient of the variable or variables with highest power.
Name = Binomial (as it has two terms)
Degree= 5 (power of x)
Leading Coefficient = 4 (coefficient of )
Name = trinomial (as it has 3 terms)
Degree = 3 (highest power of x)
Leading Coefficien= 7 ( coefficient of )
Name= Monomial (as it has 1 term)
Degree= 5+3+1= 9 [Addition of power of all variables]
Leading Coefficient = 18
