Answer:
B) 4 inches
Step-by-step explanation:
Since ABC is congruent to EFG then AB is congruent to EF, and BC is congruent to FG.
BC = 4 in
FG = 4 in
Answer:
scalene triangle
Step-by-step explanation:
A scalene triangle has three different angles and none of its sides are equal in length.
If 
has to be a solution of the equation, just plug it in:
![(\pm 15i)^2 + [1] = 0 \iff -225 + [1] = 0 \iff [1] = 225](https://tex.z-dn.net/?f=%20%28%5Cpm%2015i%29%5E2%20%2B%20%5B1%5D%20%3D%200%20%5Ciff%20-225%20%2B%20%5B1%5D%20%3D%200%20%5Ciff%20%5B1%5D%20%3D%20225%20)
So, the solutions of
are 
Answer:
Option A. 8x² - 25x + 7.
Step-by-step explanation:
The given polynomials are
A = 3x -4
B = x + 7
C = x² + 2
Now we have to find the simplest form of A² - (B + C)
A² = (3x - 4)² = 9x² + 16 -24 x
B + C = x + 7 + x² + 2 = x² + x + 9
Now A² - (B + C) = 9x² + 16 -24x -(x² + x + 9)
= 9x² -24x + 16 - x²- x - 9
= 8x² -25x + 7
Therefore Option A. 8x² - 25x + 7 is the answer.
