●) -2 (3a - 4b)-6a + 3b
-2 (9a-7b)
●) 10 - 6a - 4y - (-2a) + 9y
10 - 6a - 13y - (-2a)
●) 9 (2x-6) - 3 (5-4x
12 (6x-11)
All I did was combine the numbers with the same variable
Answer:
option A and E
Step-by-step explanation:

Answer:

Step-by-step explanation:
We are given
zeros as -10 and 7/8
now, we can set up function as

now, we are given that
leading coefficient is 8
so, a=8
now, we can plug it

now, we can simplify it

so, we get

Answer:
3√5
Step-by-step explanation:
d = √(difference of x)² + (difference of y)²
d = √(7 - 4)² + (5 - (-1))² = √9 + 36 = √45 = 3√5
