How do I Express 18+24 as the product of the GCF and another sum
svp [43]

Answer:

6(3+4)

Step-by-step explanation:

We are asked to represent 18+24 as the product of the GCF and another sum.

First of all, we will find the greatest common factor of 18 and 24.

Factors of 18: 1, 2, 3, 6, 9, 18.

Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24.

We can see that greatest common factor of 18 and 24 is 6. Let us write our given expression as product.

6\cdot 3+6\cdot 4

Factor our 6:

6(3+4)

Therefore, our required expression would be 6(3+4).

Does anyone know the answer to these two problems?
Nady [450]

Answer:

8) -8, -9

9) 4, $ \frac{1}{2} $

Step-by-step explanation:

8) x² + 12x + 27

Solutions of a polynomial means the values of $ x $ such that the polynomial becomes zero. $ i.e., y = 0 $.

We use the following formula to determine the solutions of a quadratic equation of the form: $ ax^2 + bx + c = 0 $

    $ \implies x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} $

In this equation, $ a = 1; b = 12; c = 27 $

Substituting in the formula, we have:

$ x = \frac{-12 \pm \sqrt{144 - 108}}{2} $

$ \implies x = \frac{-12 \pm 6}{2} $

Taking 2 common outside we get:

$ x = - 6 \pm 3 $

Therefore, we get two solutions viz, x = -3, -9.

9) 2x² - 9x + 4 = y

X- intercepts of a polynomial means the value of x such that y = 0. It means the roots of the polynomial.

Solving the equation using the formula above, we get:

$ x = \frac{-(-9) \pm \sqrt{81 - 32}}{2(2)} $

$ \implies x = \frac{9 \pm 7}{4} $

The values of x = 4, $ \frac{1}{2} $.

Hence, the answer.
