The surface area of rectangular solid is 208 square centimeter
The volume of rectangular solid is 192 cubic centimeter
<h3><u>Solution:</u></h3>
Given that rectangular solid has sides of 4 cm, 6 cm, and 8 cm
To find: surface area and volume of rectangular solid
Length = l = 4 cm
Width = w = 6 cm
Height = h = 8 cm
<h3><em><u>
The formula to find the surface area of a rectangular prism is:</u></em></h3>
Surface Area = 2wl + 2lh + 2hw
where w is the width, the l is the length, and the h is the height.

Thus the surface area of rectangular solid is 208 square centimeter
<h3><em><u>
The formula for volume of rectangular solid is:</u></em></h3>


Thus the volume of rectangular solid is 192 cubic centimeter
Answer:
9x+4y-17z
Step-by-step explanation:
first open brackets with d signs
dat is= 4x+2y-6z+5y-2z+7x-9z-2x-3y
collect like terms and = 4x+7x-2x+2y+5y-3y-6z-2z-9z= 9x+4y-17z
Let
x = points that a student needs to score on a test
p = points worth the exam.
to find how many points to student needs to score on a test to get a test score of 78%. it will be given by
x = 0.78 * p
Thus, in a 50-point test, the number of points the student needs to get to get a test score of 78% will be
x = 0.78 * 50 = 39 points.
The focus it the point, so all you have to do is plot the focus on a graph. Then, draw a line to the point of origin and calculate the equation. This equation in slope intercept form would be y=-x+0
