Answer:
33, 9
Step-by-step explanation:
I33-21I=12
I9-21I=
I-12I=12
Every SUM of an absolute value will always be positive!!
It’s 45, since the bottom corner is 90, the top one is 45 bc if you turn it into a rectangle it has to be 90 also and half of that is 45, 90 plus 45 is 135 and all the angle of a right triangle make 180, so 180 minus 135 is 45
Answer:
I hope it requires the picture I have drawn.
a = - 15 and b = - 9
distribute the left side of the equation
- 15x² - 25x - 5b
for - 15x² - 25x - 5b and ax² - 25x + 45 to be equal then the coefficients of like terms must be equal, hence
- 15x² = ax² ⇒ a = - 15
- 5b = 45 ⇒ b = - 9
