Find the product. (r + s)2

Mathematics
1 answer:
mario62 [17]3 years ago
3 0
When you've got a squares bracket, this simply becomes the bracket twice, therefore, (r+s)2 becomes (r+s)(r+s)
You've then go to use FOIL, and this gives you r^2+rs+sr+s^2, and this cannot be simplified any further.
Therefore, the product of this is r^2 + s^2 + rs + sr
Hope this is what you're looking for :)

1.) v=(l)(w)(h)
V=(9)(9)(9)
V=(81)(9)
V=729in^3

2.) (I forget if this is the real equation to this but this would give you the same answer)

V=(l)(w)(h)
————
2
V=(8)(6)(12)

I need help with point slope formula bad
NISA [10]
Ok so this question:
y + 1 = - ( x - 2 )        (distribute the negative inside the parenthesis)
y + 1 = -x + 2             (substitute the y= -1)
-1 + 1 = -x + 2
0 = -x + 2                   (take two to the other side)
-2 = -x                        (divide the negative away from x)
2 = x

Jenny's parents deposit $10,000 for her college tuition in an account with a 3% simple interest rate. How long will it take to e
KiRa [710]
Ok so <span>Interest = Principle * rate * time P = 10,000 R = 3% = 0.03 T (we need to solve for t I = 3600 now we sub.. 3600 = (10,000)(0.03)(t) 3600 = 300t -- divide both sides by 300 3600/300 = t 12 = t check.. I = prt 3600 = (10000)(0.03)(12) 3600 = (300)(12) 3600 = 3600 (correct) It would take 12 years</span>
