Expand and combine the like terms (2-3d^3)^2

VMariaS [17]

Answer:

Option 4. $4-12d^3+9d^6$

Step-by-step explanation:

$(2-3d^3)^2 = (2-3d^3)(2-3d^3)$

$= 4-6d^3-6d^3+9d^6$

$=4-12d^3+9d^6$

Note: Don't just square each term inside the brackets as it will give you an incorrect result. Write it out as a product to avoid making this mistake if you are not familiar with expanding binomial products.

Hope this helps :)

Y=3x+13<br> 2x=y-9<br> Solve for x and y points using addition method

GrogVix [38]

$y=3x+13 \\
2x=y-9 \ \ \ |-y-2x \\ \\
y=3x+13 \\
\underline{-y=-2x-9} \ \ \ \hbox{add the sides} \\
y-y=3x-2x+13-9 \\
0=x+4 \\
x=-4 \\ \\
y=3x+13=3 \times (-4)+13=-12+13=1 \\ \\
\boxed{(x,y)=(-4,1)}$
