Answer:

Final answer is x^2-x-12.

Step-by-step explanation:

Given expression is \left(x-4\right)\left(x+3\right).

Now we need to find the product of the given expression \left(x-4\right)\left(x+3\right).

\left(x-4\right)\left(x+3\right)

=x\left(x-4\right)+3\left(x-4\right)

=x^2-4x+3x-12

combine like terms

=x^2-1x-12

=x^2-x-12

Hence final answer is x^2-x-12.

ANSWER

(x-4)(x+3) =  {x}^{2}   - x - 12

EXPLANATION

The given product is (x-4)(x+3)

We expand using the distributive property to obtain:

(x-4)(x+3) = x(x + 3) - 4(x + 3)

Expand the parenthesis to obtain:

(x-4)(x+3) =  {x}^{2}  + 3x- 4x  - 12

Combine the similar terms to get:

(x-4)(x+3) =  {x}^{2}   - x - 12

The hypotenuse of a 30o-60o-90o triangle measures 4 square 3 inches. What is the length of the shorter leg?
Fofino [41]

<u><em>Answer:</em></u>

The shorter leg is 2\sqrt{3} inches

<u><em>Explanation:</em></u>

The 30°-60°-90° is a special type of right-angled triangles

<u>It has the following special side length:</u>

The length of the side opposite to the 30° is \frac{1}{2} the length of the hypotenuse

The length of the side opposite to the 60° is \frac{\sqrt{3} }{2} of the hypotenuse

<u>Now, we know that</u> the lengths of the sides in a triangle are proportional to the angles

<u>This means that</u> the shortest side will be the one opposite to the smallest angles

In our case, the shortest side will be the one opposite to the 30° angle

We are given that the hypotenuse of the triangle is 4\sqrt{3} in

<u>From the above:</u>

Shorter leg = leg opposite to 30° = \frac{1}{2} * hypotenuse = \frac{1}{2} * 4\sqrt{3} = 2\sqrt{2} inches

Hope this helps :)

What times what equals 216
BARSIC [14]
<span>The question ask us to find the products which equals 216. First we have to factorize 216: 216 = 2*2*2*3*3*3. So: 216 = 1 * 216; 216 = 2 * 108; 216 = 3 * 72; 216 = 4 * 54 ; 216 = 6 * 36; 216 = 8 * 27; 216 = 9 * 24 ; 216 = 12 * 18. And because of a commutative property: 216 = 18 * 12 ; 216 = 24 * 9 ; 216 = 27 * 8 ; 216 = 36 * 6 ; 216 = 54 * 4 ; 216 = 72 * 3 ; 216 = 108 * 2; 216 = 216 * 1.</span>
