Answer:
no solution
Step-by-step explanation:
6x - 3y = 7 → (1)
- 2x + y = - 8 → (2)
multiplying (2) by 3 and adding to (1) eliminates the variables
- 6x + 3y = - 24 → (3)
add (1) and (3) term by term
0 + 0 = - 17
0 = - 17 ← false statement
This indicates the system has no solution
An acute angle can also be made inside of that type of triangle.
The answer is 21, because if you multiply 21 times 3 you get 63
A solid whose top and base are congruent polygons and lateral faces are parallelograms is called <u>prism</u>.
<h3>
What is prism?</h3>
A prism is a polyhedron made up of n parallelogram faces that connect the n-sided polygon basis, the second base, which is a translated duplicate of the first base, and the n faces. Translations of the bases are found in all cross-sections that are parallel to them.
<h3>What is
congruent polygons?</h3>
If the corresponding sides and angles of two polygons are identical, then the polygons are congruent. It should be noted that two sides are congruent if their lengths are the same, and that an angle is congruent if its measure is the same.
