Which expressions are equivalent to -2.5(1-2n) - 1.5n

Keith_Richards [23]

Answer:

-5n - 4

Step-by-step explanation:

The goal is to simplify this expression.

1. Distribute

-2.5 * 1 = -2.5

-2.5 * 2n = -5n

Now, we have

-2.5 - 5n - 1.5

2. Combine like terms

-2.5 + (-1.5) = -4 (+ * - = - The - cancels out the +)

3. Put it together

-5n - 4

I hope I helped!

How many real solutions does this system of equations have? x2 +3 = y<br> 3х — у+1 = 0

konstantin123 [22]

Answer:

Step-by-step explanation:

y = x²+3

y = 3x+1

x² + 3 = 3x +1

x² - 3x + 2 = 0

Factor the expression completely.

densk [106]

Answer:

$\fbox{\begin{minipage}{13em}Option D: 2(3x + 4)(3x - 4)\end{minipage}}$

Step-by-step explanation:

$A = 18x^{2} - 32\\$

Find the sharing components:

<=> $A=2*9*x^{2} - 2*16$

Apply the inverse of associative property:

<=> $A = 2(9x^{2} - 16)$

Identify two square components inside the parenthesis:

<=> $A = 2((3x)^{2} - 4^{2} )$

Factorize:

<=> $A = 2(3x + 4)(3x - 4)$

=> Option D is correct

Hope this helps!
