Step-by-step explanation:
<u>Step 1: Distribute</u>



<u>Step 2: Add 6 to both sides</u>


<u>Step 3: Subtract 2x from both sides</u>


<u>Step 4: Divide both sides by 10</u>


Answer: 
Diagonal of the rectangular prism=√(l²+w²+h²)
√(l²+w²+h²)=√(100+25+64)=√189 cm
Answer:
43.5=67.5
Step-by-step explanation:
19.5+24=43.5
43.5+7.5=51
=
19.5+24= 43.5
43.5+24=67.5
This is an arithmetic series, where S5 means the sum of the first 5 numbers in the series. The general formula is:
Sn = (n/2)(a1 + an)
So,
a1 = 1 + 5/2(1) = 3.5
a5 = 1 + 5/2(5) = 1.5
S5 = (5/2)(3.5+1.5)
S5 = 12.5
<em>The answer should be 12.5</em>
The coordinates of point F are 4 and negative 2.5. Option C is correct.
<h3>What is the best way to understand the Cartesian coordinate plane?</h3>
A Cartesian coordinate plane is a two-dimensional plane with infinite dimensions. On an endless 2d plane, any two-dimensional figure may be drawn. A location is assigned to each point on a Cartesian plane.
It is the perpendicular distance between that point and the horizontal and vertical axes, which are commonly referred to as the x-axis and y-axis.
The location is then written as (a,b), where 'a' is the point's shortest distance from the y-axis, 'b' is the point's shortest distance from the x-axis, and 'c' is the point's shortest distance from the x-axis.
'c' is the point's shortest distance from the x-axis, and 'c' is the point's shortest distance from the x.
The coordinates of point F are 4 and negative 2.5.
Hence, the Option C is correct.
