Answer:
Step-by-step explanation:
(g-f)(x) = 9x³ - 4x² + 10x - 55 - [ 4x³ +3x² - 5x + 20]
To remove the parenthesis, take - inside, multiply f(x) by -1
= 9x³ - 4x² + 10x - 55 - 4x³ - 3x² + 5x - 20
Now, bring like terms together,
= 9x³ - 4x³ - 4x² - 3x² + 10x + 5x - 55 - 20
= 5x³ - 7x² + 15x - 75

−211=−108 is false, there is no solution.
Answer:
False
Step-by-step explanation:
The two triangles given in the diagram are congruent.
This means that they are equal in all respect.
The sides and the angles are all equal.
This means that m<T=80
When TR is 46 then it means 64=36, which is not True
Therefore we cannot assume that TR=46
