Answer:

3(x - 3)(7x^2 + 5).

Step-by-step explanation:

21x3 - 63x2 + 15x - 45

The greatest common factor of the constants is 3, so we have:

3(7x^3 - 21x^2 + 5x - 15)

Now we factor this by grouping:

= 3 [7x^2 (x - 3) + 5(x - 3)

= 3(x - 3)(7x^2 + 5).

Three vertices of a rectangle are (–2, 1), (–2, –3), and (4, –3)

Tpy6a [65]

The answer is C
it's easier if you graph it
we know that the x of the unknown vertice is 4, because this is a rectangle and that vertices has to be on the same x line as the point below.
y of the unknown vertice has to be 1 because the vertice to the left needs to be on the same y line as the unknown vertice

Solve the equation given in Exercise 15 with and without using the LCD of the fractions. Are your answers the same?

Colt1911 [192]

Without LCD :
1/2(4x + 6) = 1/3(9x - 24)
2x + 3 = 3x - 8
2x - 3x = -8 - 3
-x = - 11
x = 11

with LCD :
1/2(4x + 6) = 1/3(9x - 24) ...multiply by 6
3(4x + 6) = 2(9x - 24)
12x + 18 = 18x - 48
12x - 18x = -48 - 18
-6x = - 66
x = -66/-6
x = 11

Yes, the answers are the same :)

“The sum of half a number and 12 is 6”

lianna [129]

<u>Solution</u> :

Let, the number be A

Given, A/2 + 12 = 6

⇒ (A + 24)/2 = 6

⇒ A + 24 = 12

⇒ A = 12 - 24

⇒ A = - 12

∴ the required number is (- 12). (Ans.)
