0.36(18)+0.04x=0.12(24+x)
zhuklara [117]

Answer:

x = 45

Step-by-step explanation:

0.36(18) + 0.04x = 0.12(24 + x)

6.48 + 0.04x = 2.88 + 0.12x

0.04x - 0.12x = 2.88 - 6.48

-0.08x = -3.6

0.08x = 3.6

x = 3.6/0.08

x = 45

kipiarov [429]

Answer:

Notation Rule A notation rule has the following form ry−axisA → B = ry−axis(x,y) → (−x,y) and tells you that the image A has been reflected across the y-axis and the x-coordinates have been multiplied by -1. Reflection A reflection is an example of a transformation that flips each point of a shape over the same line.

What is the missing constant term in the perfect square that starts with x^2-12x
Ipatiy [6.2K]

Essentially, we are trying to find the missing constant term of (x - a)^2 (remember that we are subtracting a due to the negative sign in front of the second term). Let's expand this to see what we can work with:

(x - a)^2

  • Set up

x^2 - ax - ax + a^2 = x^2 - 2ax + a^2

  • FOIL and simplify

Now, we know the second term is 12x, so let's set the second term in the polynomial we just found equal to 12x:

2ax = 12x

  • Set up

2a = 12

  • Divide both sides of the equation by x

a = 6

  • Divide both sides of the equation by 2

We have found a = 6. We know the missing constant term is a^2, according to the polynomial we found earlier. Thus, the missing term is:

a^2 \Rightarrow 6^2 = 36


The missing constant term is 36.
