Breaking Apart Strategy is an easy way to find multiplication, even though those are difficult ones. This is a great strategy for breaking apart harder multiplication problems, so the result you get is the same as if you are multiplying the original equation.
<span>
For example, suppose you want to get this multiplication:
</span>
<span>
So eight times seven is a tricky one sometimes. Maybe we forget this multiplication so let's break it apart. Therefore, let's break apart seven, that is:
</span>
<span>
This is true because five and two makes seven. Therefore, the new equation is:
</span>
<span>
Applying distributive property:
</span>
<span>
So:
</span>
<span>As you can see the multiplication was obtained in a easy way.

To solve this question, first we multiply.
Before anything else, we must find the area of the triangle on either side of the prism. The measurements are 24 in. by 7 in., so we do that, which gives us 168 in.²
Then, we multiply this by the base length, which is 20 in.
168x20=3360, so the correct answer is B, 3,360 in³.
Hope I helped!
Answer:
Step-by-step explanation:
Here the coefficients of this quadratic equation are {7, -1, -3}. Note that the given equation must be rewritten in standard form: 7x^2 - x - 3.
Then the discriminant, b^2 - 4ac, is (-1)^2 - 4(7)(-3), or 1 + 84, or 85. Because this discriminant is positive, the given quadratic has two real, unequal roots. These roots are:
-(-1) ± √85
x = ------------------
14
or:
1 ± √85
x = ------------------
14
