3u^2+8u-3
with grouping, we have to find 2 numbers which add up to 8 and multiply to 3*(-3)= -9.
testing, we find that 9 and -1 add up to 8 and multiply to -9.
so now we can write the original equation as
3u^2-u+9u-3
you can factor the terms in pairs:
u(3u-1)+3(3u-1)=
(u+3)(3u-1)
I don't know what ur supposed to do but if u add them it equals 31.9 sorry if that's not what you have to do
Answer:
=−12n6t5
Step-by-step explanation:
6t4n3((−2t)(n3))
1: First step is to get the whole equation that is 6t4n3((−2t)(n3)) in a short form and simplify it.
2: Your answer will equal as =−12n6t5.

Answer:
72 ft.
Step-by-step explanation:
In this problem, we are looking for the perimeter of the kennel. The perimeter of a rectangle has the formula, 
, where <em>l</em> represents the length of the rectangle and <em>w</em> represents the width of the rectangle. We are given both the length and the width (or simply the two sides) of the rectangle, and all we need to do is plug it into the formula!
<u>Therefore, it would require 72 ft. of fencing to enclose the kennel.</u>

Answer:
x=13
y= -9
(13, -9)
Step-by-step explanation:
If we are solving using the substitution method, we can take the first equation and set it to y so y=4-x.
Then, we can take that equation and plug it into the bottom one so
3x+4(4-x)=3
Simplify:
3x+16-4x=3
-x=-13
x=13
We can then plug 13 into any of the two given equations (I am just going to plug it into the top one)
So, 13+y=4 which y= -9
