Answer:
-33
Step-by-step explanation:
27-(-3)=30
-3-30=-33
AB/DE = BC/EF
CA/FD = AB/DE
MJ/QN = JK/QP
LM/PQ = MJ/OP
Answer:
n+14
Step-by-step explanation:
To write an expression, we often have to interpret a written phrase. For example, the phrase “6 added to some number” can be written as the expression x + 6, where the variable x represents the unknown number.
Answer:
<h3>
720 different ways</h3>
Step-by-step explanation:
Permutation has to do with arrangement. If r objevt selected from n pool of objects are to be arranged in a straight line, this can be done in nPr number of ways.
nPr = n!/(n-r)!
If 5 people are to be chosen and arranged in a straight line, if there are 6 people to choose from, this can be done in 6P5 numbe of ways.
6P5 = 6!/(6-5)!
6P5 = 6!/1!
6P5 = 6*5*4*3*2*1
6P5 = 720 different ways

The question leaves you with the partially factored equation:
8x(7x-1) - 1(7x-1)
Now if you look at the partially factored equation, you'll see that both terms have (7x-1) as one of their factors. So let's take that (7x-1) as a factor and divide both terms by (7x-1), giving us
(8x(7x-1) - 1(7x-1)) / (7x-1)
The (7x-1) factors cancel out, leaving us with
(8x - 1)
So our 2 factors are (7x-1) and (8x-1).
Looking at the available options, the only correct one is
(8x-1)(7x-1)</span>
