Answer:
Step-by-step explanation:
The best way to do this is to first remove the parenthesis by distributing the negative into them. Then we will group the like terms together, moving their respective signs with them, then we will simplify. For the first one, after distributing the negative into the parenthesis (remember that a negative in front of a set of parenthesis containing a polynomial changes the signs in front of each term within the polynomial; negatives become positives and positives become negatives):
and then grouping like terms next to each other:
(this step is not completely necessary; I just encourage new learners to do it so as to not miss any of the like terms)
The above then simplifies to
The next one, after distributing the negative into the parenthesis:
and then grouping like terms next to each other (remember to move their signs with them!):
which simplifies to
Now for the last one:
and
which simplifies to
Answer:
<h3>The surface area of the prism is A prism=204m2</h3>
Step-by-step explanation:
Area is the space that is contained in a two-dimensional figure.
Surface area is the total area of all of the sides and faces of a three-dimensional figure.
To find the surface area, the area of each face is calculated and then add these areas together.
To find the area of a rectangle, multiply the length by the width .
From the graph the length of the rectangle is 10 m and the width is 8 m. Therefore, the area of the bottom face is
From the graph the length of the rectangle is 10 m and the width is 5 m. Therefore, the area of one of the rectangular side faces is
To find the area of a triangle use the following formula where b is the base and h is the height.
From the graph the base of the triangle is 8 m and the height is 3 m. Therefore, the area of one of the triangular faces is
The surface area of the prism is the sum of the area of the bottom face, the area of the two rectangular side faces, and the area of the two triangular faces
