PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

Mathematics
1 answer:
Alenkasestr [34]3 years ago
6 0

Answer:

A = -10

Step-by-step explanation:

x^2 + 10x + 24 = 0

To find the roots, we need to factor the equation.

What 2 numbers multiply to 24 and add to 10

6*4 = 24

6+4 = 10

(x+6) (x+4)=0

Using the zero product property

x+6 = 0  x+4 = 0

x = -6   x = -4

We want the sum when the roots are added

-6+ -4 = -10

Simplify x^2-9x-22/x-11
OleMash [197]

Answer:

x^2-11/-8x

Step-by-step explanation:

We can solve this equation easily by using PEMDAS, or order of operations.

<u>Parenthesis</u>

<u>Exponents</u>

<u>Multiplication>Division (Depends on which comes first left to right)</u>

<u>Addition>Subtraction (See multiplication>division)</u>

Now that we know the order of the operations, we can solve.

First, we cant solve for x^2 because we dont know the value of x, so well leave that alone. Same with 22/x. All we can do is use the commutative property.

So our equation is now x^2-11/-8x

Hope this helps!

Simplify quantity 10 x squared minus 32 end quantity over 4 quantity 5 x squared minus 32 end quantity over 2, quantity 5 x squa
irina1246 [14]

Answer:

Option B.

Step-by-step explanation:

The given expression is

\dfrac{10x^2-32}{4}

We need to find the simplified form of given expression.

Taking out GCF from the numerator.

\dfrac{2(5x^2-16)}{4}

Cancel out common factors.

\dfrac{5x^2-16}{2}

The expression \dfrac{5x^2-16}{2} is the simplified form of given expression.

Therefore, the correct option is B.
