Answer:
-2
Step-by-step explanation:
- 5x + 8 = 18
Take + 8 to the right hand side, it turns negative i.e -8
-5x = 18 - 8
-5x = 10
Divide both sides by the coefficient of x which is -5
-5x/5 = 10/-5
x = -2
D(e^(In(x))^2)/dx = 2 In(x) * 1/x * e^(ln(x))^2 = (2e^(ln(x))^2 * In(x)) / x
Given that both triangles are similar and have a scale of 5:2, therefore the true statement about the proportions of the sides is:
B. AC/DF = 5/2
<h3>What are Similar Triangles?</h3>
- Similar triangles have corresponding side lengths that are proportional in length.
- Similar triangles have same shape but are of different sizes.
Thus, given that both triangles are similar and have a scale of 5:2, therefore the true statement about the proportions of the sides is:
B. AC/DF = 5/2

The answer is true.But I am not sure if it can collect data
The rule about dividing is that you have to flip the divisor, so that gives us 4x+1/6x * 3x-1/x
Now we just multiply the numerator by the numerator and the denominator by the denominator.
Let’s multiply the numerators first,
(4x+1)*(3x-1)
Use distributive property,
12x^2-4x+3x-1
Collect the terms and simplify,
12x^2-x-1
We can already tell that our answer is A, but let’s solve the denominators just to check.
6x*x
6x^2
We are left with 12x^2-x-1/6x^2
So your final answer is A
