Step-by-step explanation:
d=(3/4)-(1/4)=(5/4)-(3/4)=(7/4)-(5/4)=1/2
then it is an arithmetic sequence
by using this equation :
a(n) = a1 +(n-1)d
and we have : a1=(1/4), d=(1/2)
So:
Explicit formula: a(n) = (1/4) +(n-1)*(1/2)

The answer is 54 feet because 15+15+12+12=54
Hope this Helps :D
7n - 2 - (3n - 9 - 5)
= 7n - 2 - (3n - 14)
= 7n - 2 - 3n + 14
= 4n + 12
Hope it helped!
Option B
The volume of sand he will need to fill half of the sandbox is 55.35 cubic feet
<em><u>Solution:</u></em>
<em><u>The volume of rectangular prism is given as:</u></em>
From given,
Area of base = 49.2 square feet
Height = 2.25 feet
<em><u>Substituting the values we get,</u></em>
Thus volume of sand box is 110.7 cubic feet
Mr. Berger plans to fill the sandbox half full of sand
So find half the volume
volume of sand he will need to fill half of the sandbox is given as:
Thus the volume of sand he will need to fill half of the sandbox is 55.35 cubic feet
<span>Triangles can only congruent if all its corresponding sides and angles are congruent. Therefore, two triangles in which only one of them is isosceles cannot be congruent because an isosceles triangle has two equal sides and a non isosceles triangle does not have this property therefore one or two corresponding sides cannot be congruent. an exception to this is if the two said triangles are both equilateral then they can be congruent because an equilateral is considered isosceles.
