Answer:
The square cake is larger by 31 in^2
Step-by-step explanation:
A round cake has a circular area on top.
We need to find the radius
d= 2r
8 = 2r
r=4
The area of the circle is pi r^2
A = 3.14 * 4^2
A = 3.14 *16
= 50.24
The area of the square cake is
A =s^2
A = 9^2
A = 81
The square cake is larger
The difference is Asquare - A round
81 -50.24
30.76
Which is close to 31 in ^2
(4xy - 3z)²
(4xy - 3z)(4xy - 3z)
4xy(4xy - 3z) - 3z(4xy - 3z)
16x²y² - 12xyz -12xyz + 9z²
16x²y² - 24xyz + 9z², a perfect square trinomial.
Answer:
Step-by-step explanation:
3x²+11x-4
when splitting the middle term
it becomes
3x²+12x-1x-4
=3x(x+4)-1(x+4)
(3x-1)(x+4)
either 3x-1=0 then x=1/3
or x+4=0 then x= -4
m=1/3
n=-4
therefore
value of m divided n plus n dividedm=1.25
