Answer: 2b-21a
Step-by-step explanation:
Hello!
So, here you want to do the distributive property.
Start on the left side of the + sign...
-3*u = -3u
-3*3 = -9
So we now we have:
(-3u + -9) + 4(4u + 2)
Now we focus on the right side of the + sign...
4*4u=16u
4*2=8
So now we have:
(-3u + -9) + (16u + 8)
Now you want to combine like terms. Start by adding terms with the same variable. So, we need to add -3u and 16u
<em>-3u + 16u =</em> 13u
Now we have:
13u + -9 + 8
Now add the constants, -9 + 8
-9 + 8 = -1
So, the simplified expression would be:
13u - 1 or 13u + -1
Answer:12.5 times out of 50
Step-by-step explanation:think about it add tails and 2
2z=42 then 2z/2=42/2 so z=21
