Answer:
=21 + 3x
Step-by-step explanation:
use distributive property
=3(7 + x)
=21 + 3x
Answer: 49
Step-by-step explanation:
Given
The dimension of the block is ![24.5\ in.\times12.5\ in.\times 8\ in.](https://tex.z-dn.net/?f=24.5%5C%20in.%5Ctimes12.5%5C%20in.%5Ctimes%208%5C%20in.)
Each vase requires
of clay
The volume of clay block is
![\Rightarrow V=24.5\times 12.5\times 8\\\Rightarrow V=2450\ in.^3](https://tex.z-dn.net/?f=%5CRightarrow%20V%3D24.5%5Ctimes%2012.5%5Ctimes%208%5C%5C%5CRightarrow%20V%3D2450%5C%20in.%5E3)
Number of vases that can be made
![\Rightarrow n=\dfrac{2450}{50}\\\\\Rightarrow n=49\ \text{Vases}](https://tex.z-dn.net/?f=%5CRightarrow%20n%3D%5Cdfrac%7B2450%7D%7B50%7D%5C%5C%5C%5C%5CRightarrow%20n%3D49%5C%20%5Ctext%7BVases%7D)
Thus, 49 vases can be made
Ho ho ho, lets get this party started
ok so I'm just really excited to use this stuff that I just learned
so
multiplicites
if a root or zero has an even multilicity, the graph bounces on that root
if the root or zero has an odd multiplicty, the graph goes through that root
so
roots are
-1
2
4
multiplicty is how many times it repeats
2 has even multiplity
we just do 2 is odd and 1 is even so
for roots, r1 and r2, the facotrs would be
(x-r1)(x-r2)
so
(x-(-1))^1(x-2)^2(x-4)
(x+1)(x-2)^2(x-4)
this is a 4th degre equaton
normally, it is goig from top right to top left
it is upside down
theefor it has negative leading coefient
y=-k(x+1)(x-4)(x-2)^2
1 foot is 12 inches
12•12•12 is 1,728 cubic inches
this can help you convert because you now know how many inches are in a cubic foot, and you can divide the amount of cubic inches by 12 to find the cubic feet
