Answer:
Step-by-step explanation:
okay, so here are a few methods you can use.
___
1) +
x + 7 = 10 so because this is addition we use the reverse, subtraction. So
x - 7 = 10 - 7 and that equals to 3.
2) -
x - 2 = 10 so because this is subtraction we do the reverse, addition.
x + 2 = 10 + 2 and that equals to 12.
3) x
x times 3 = 21 because this is multiplying we divide.
x/3 = 21/3 and that would be 7.
4) /
x/2 = 10 same as above, reverse is multiplying.
x times 2 = 10 times 2 and thats 20.

Let x represent the side length of the squares.
We have been given that an open box is made from an 8 by ten-inch rectangular piece of cardboard by cutting squares from each corner and folding up the sides. We are asked to find the volume of the box.
The side of box will be 
and 
.
The height of the box will be 
.
The volume of box will be area of base times height.
Now we will use FOIL to simplify our expression.
Now we will distribute x.
Therefore, the volume of the box would be .
So the answer is
(<span>x^2 plus or minus 6)(x^2 plus or minus 6)
an easy way to do this is to only look at plus or minus 6
x^4 <u><em>- 12</em></u>x^2 + <u><em>36 (-12 and 36)
</em></u><em />
<u><em /></u>6 x 6 = 36
<em />6 + 6 </span>≠ -12 (x^2 + 6)(x^2 + 6) is incorrect
<span><u><em>
</em></u><em><u /></em><u />6 x -6 </span>≠ 36
<span><em />6 + -6 </span>≠ -12 (x^2 - 6)(x^2 + 6) is incorrect
<span><em /><em>
</em><em />-6 x -6 = 36
<em />-6 + -6 = -12 </span><span>(x^2 - 6)(x^2 - 6) is correct
</span><u><em>
the answer is (1)

Answer:
Step-by-step explanation:
To write an algebraic expression from words, translate each word into a symbol. Division can be shown with a division sign or a fraction sign. Create a fraction with a 12 in the numerator and the variable t in the denominator.
Answer:
It was a rainy day
, but Joan and I had planned a trip. Joan wanted to go to the beach for a swim. I wasn't sure if we should go.
"I think we should wait a little longer
, at least until the rain shows some signs of slowing down," I suggested.
"We can't swim without getting wet anyway," replied Joan, questioning my choice of swimsuit
, the one my mom had bought at a secondhand store.
