Answer: a= 16
Step-by-step explanation:
We have the following expression:

To find the value of the coefficient "a" you must use the distributive property to multiply the expression:

until you transform it to the form:

Then we have

Therefore the value of a in the polynomial is 16
16/20 = 8(2)/10(2) = 8/10. 8/10 can also be further reduced to 4/5.
From the amounts that are given, the ratio of the earnings will be 3:2:1.
<h3>How to calculate ratio</h3>
From the information, the eldest earns R270, the middle child earns R180 and the youngest earns R90.
Therefore, the common factor to the numbers will be 90. Therefore, the ratio will be:
270/90 = 3
180/90 = 2
90/90 = 1
The ratio is 3:2:1.

Answer:
units.
Step-by-step explanation:
Let x be the width of rectangle.
We have been given that the length of garden is 2 units more than 1.5 times it’s width. So length of the rectangle will be:
.
To find the length of total fencing we need to figure out perimeter of rectangle with width x and length
.
Since we know that perimeter of a rectangle is two times the sum of its length and width.

Upon substituting length and width of garden in above formula we will get,


Upon using distributive property we will get,


Therefore, the length of required fencing will be
units.
