Answer:
An example below
Step-by-step explanation:
5(4a + 7(a + 2b))
First simply the inside bracket using distributive property:
7(a + 2b)
7(a) + 7(2b)
7a + 14b
5(4a + 7a + 14b)
5(11a + 14b)
Use distributive property again
5(11a) + 5(14b)
55a + 70b
Answer:
y=-2/3x+6
Step-by-step explanation:
Graph it
Answer:
area ≈ 6.3 units²
Step-by-step explanation:
Calculate the area (A ) of the sector as
A = area of circle × fraction of circle
= πr² × 
= π × 4² × 
= 16π ×
← cancel 8 and 16 by 8, leaving
A = 2π ≈ 6.3 units² ( to 1 dec. place )
B is the correct if this multiple choice
Answer:

And we can subtract 4x in both sides and we got:

Now we can subtract in both sides 16 and we got:

And if we divide both sides by 4 we got:

And the best solution would be:
-7
Step-by-step explanation:
For this case we assume the following equation:

And we can subtract 4x in both sides and we got:

Now we can subtract in both sides 16 and we got:

And if we divide both sides by 4 we got:

And the best solution would be:
-7
