Answer:
4y^2-12y
Step-by-step explanation:
y^2+4y-16y+3y^2
=y^2+3y^2+4y-16y
=4y^2+4y-16y
=4y^2-12y
Answer:
12
Step-by-step explanation:
Length of one of the boards = 8 feet
Converting to inches

One cut is 16 inches
So, we divide the length of the board by 16

So, one board is cut into 6 pieces.
The other board is also 8 feet long.
So, the number of pieces the other board is cut into is also 6.
Hence, a total of
pieces of each 16 inches long can be cut from the two boards.

Answer:
<h2>
A. ¹²/₅</h2>
Step-by-step explanation:
There is no solution for system of equations:
if: 
so first, we we need to transform the equations to the form where the coefficients at y will be the same:

Now we have b₁=b₂ and c₁≠c₂ so the system has no solution if a₁=a₂
5k = 12
÷5 ÷5
k = ¹²/₅
