Answer:
$27
Step-by-step explanation:
b will be the number of books and p will be the price, now we just use a system of equations
bp = 864
b=864/p
(b+4)(p-3) = 864
(864/p +4)(p-3) = 864
864 - 2592/p + 4p -12 = 864
864p - 2592 + 4p^2 -12p - 864p = 0
4p^2 -12p -2592 = 0
4(p^2 - 3p -648) = 0
4((p - 3/2)^2 - 2601/4) = 0 (completed the square here)
4(p - 3/2)^2 -2601 = 0
p = +/-51/2+3/2
p = 27 or -24
A negative price doesn't make sense so it's 27, now we go back to the other equation if you want to find the number of books.
b=864/p
b = 864/27
b = 32
First you do the parenthesis
then you do the exponent in the parenthesis
Then the multiplication in the parenthesis
then when you are done multiplying in the parenthesis
then u multiply the answer in the parenthesis with 1/3
and then you are done
F(x)=x²+5x+6
2·3=6
F(x)=(x+2)(x+3)
That's your answer.
Answer:
1584mm^2
Step-by-step explanation:
20 x20 = 400 and there are 3 of them
400+400+400 = 1200
1/2(16x24 ) =192 and there are 2 of them
192+192 = 384
1200+384
I assume you're asking to convert 114₅ to base 10. We have
114₅ = 1•5² + 1•5¹ + 4•5⁰
114₅ = 25 + 5 + 4
114₅ = 34
