Answer:

x = - 14

Step-by-step explanation:

23 + 4 + x = 25 - 12

Combine like terms on both sides of the equation (by adding 23 and 4 on the left-hand side, and subtracting 12 from 25 on the right-hand side):

23 + 4 + x = 25 - 12

27 + x = 13

Next, subtract 27 from both sides to solve for x:

27 - 27 + x = 13 - 27

x = - 14

Subtracting a polynomial has the same result as adding its additive inverse.

morpeh [17]

The answer is true...

Why?

Let's take (2x) as a simple polynomial. Subtracting 2x from 2x is one thing, then adding it's inverse, (-2x) yields the equation to 0. This is why it is true...

Hope this helps!! Please give me brainliest!

If -5 > a and a > b then -5 is *

Alona [7]

Answer:

greater than b

Step-by-step explanation:

We can use the transitive property for this answer. The transitive property states that if A=B, and B=C, A will always be equivalent to C. Similarly in this equation, -5 is greater than a, and a is greater than b, so -5 must be greater than b.

Someone please help me w this standard form question

Answer:

2.4 × 10⁶

Step-by-step explanation:

Given:

$\sf x=3.8 \times 10^5$

$\sf y=5.9 \times 10^4$

To calculate the value of R, substitute the given values into the given formula:

$\begin{aligned}\sf R & = \sf \dfrac{x^2}{y}\\\\ \implies \sf R& = \sf \dfrac{(3.8 \times 10^5)^2}{5.9 \times 10^4}\\\\& = \sf \dfrac{3.8^2 \times (10^5)^2}{5.9 \times 10^4}\\\\& = \sf \dfrac{14.44 \times 10^{10}}{5.9 \times 10^4}\\\\& = \sf \dfrac{14.44}{5.9} \times \dfrac{10^{10}}{10^4}\\\\& = \sf 2.4474... \times 10^{(10-4)}\\\\& = \sf 2.4474... \times 10^6\\\\\end{aligned}$

Therefore, the value of R to 1 decimal place is 2.4 × 10⁶
