Answer:
C. m<1 + m<5 = 180 (reason: they are consecutive angles, and should be congruent)
Answer:
X=3
Step-by-step explanation:
2(4x−3)−8=4+2x
2)(4x)+(2)(−3)+−8=4+2x
8x+−6+−8=4+2x
8x−14=2x+4
8x−14−2x=2x+4−2x
6x−14=4
6x−14+14=4+14
6x=18
x=3
Answer:
C. -31m⁴n - 8m²
Step-by-step explanation:
Given:
(9mn - 19m⁴n) - (8m² + 12m⁴n + 9mn)
Required:
Determine an expression equivalent to it
Solution:
(9mn - 19m⁴n) - (8m² + 12m⁴n + 9mn)
Distribute the negative sign to open the parentheses
9mn - 19m⁴n - 8m² - 12m⁴n - 9mn
Combine like terms
9mn - 9mn - 19m⁴n - 12m⁴n - 8m²
-31m⁴n - 8m²
Therefore, -31m⁴n - 8m² is an equivalent expression of (9mn - 19m⁴n) - (8m² + 12m⁴n + 9mn)
