Answer:
(9x² + 8x) - (2x² + 3x)
= 7x² + 5x
Step-by-step explanation:
(9x² + 8x) - (2x² + 3x)
open the bracket
= 9x² + 8x - 2x² - 3x
collect like terms
= 9x² - 2x² + 8x - 3x
= 7x² + 5x
Answer:
A) <Z = <N
C) ML = YX
E) <X = <L
Step-by-step explanation:
ΔLMN ≅ ΔXYZ
<L = <X
<M = <Y
<N = <Z
LM = XY
MN = YZ
LN = XZ
so answers:
A) <Z = <N
C) ML = YX
E) <X = <L
