(−6)∙(a+2b−3c−4d)−(−2)∙(−4a−3b+2c+d)
this will give us:
-6(a+2b-3c-4d)+2(-4a-3b+2c+d)
opening the parenthesis we get:
-6a-12b+18c+24d-8a-6b+4c+2d
putting like terms together we get
-6a-8a-12b-6b+18c+4c+24d+2d
simplifying the above we get
-14a-18b+22c+26d
the answer is :

Answer:
No, Yes, No, No.
Step-by-step explanation:
"It is not the case that x is equal to 100." This means that x ≠ 100.
"x is not equal to 300." The problem has nothing to do with 300. We know that x ≠ 100, but the fact that x ≠ 300 doesn't prove or deny anything about the statement x ≠ 100.
"x is equal to 100." This is the complete opposite of the original statement! If x = 100, then this completely denies or negates the fact that x ≠ 100.
"It is not the case that x is equal to 400." Again, 400 has nothing to do with the statement x ≠ 100, so the statement neither proves nor denies the statement x ≠ 100.
"x is equal to 300." Same story: 300 has nothing to do with x ≠ 100, so it doesn't change anything about x ≠ 100.
Answer:
b, 20 hours
Step-by-step explanation:
First, find out how many times 66 (what Vinny made) goes into 165. (what Vinny wants to make) the answer is 2.5. Then, multiply 8 by 2.5 as well. You get 20. The answer is b, 20.
I hope this helps!
