Move constant to the right-hand side and change its sign

2x^2 + 8 = -2 + 7
-2 + 7 = 5

Divide both sides of the equation by

x^2 + 4x = 5/2

Add (4/2^2) to both sides of the equation

x^2 + 4x + (4/2)^2 = 5/2 + (4/2)^2

factor the expression

(x + 4/2)^2 = 13/2

reduce the fraction by 2

(x + 2)^2 = 13/2

now solve equation for x

Answer:

Step-by-step explanation:

This question is a bit sloppy. In higher math courses it would not be permitted. I'll give you the general rule that applies to this question -- sort of.

If you have a triangle that hast angles of 100 50 and 30

The largest side will be opposite the 100 degree angle.

The smallest side will be opposite the 30 degree angle.

So for the question, you are intended to say that CD > AB because CD is opposite a 43 degree angle and AB is opposite a 40 degree angle.

So the answer is Since 43 > 40 then CD>AB

Help please! I’m struggling ah sksjkdkkdkd <br> -Alyssa
Maurinko [17]

He would weight 3.745 kg. Dividing it by 1,000 which is what a kg is more to a gram, 1,000 g = 1 kg. If the problem looked like 3,745. then move the dot over by how many zero's there is in 1,000, which is 3. 3.745. And sorry, but I am not sure about your other problem. But if I were to guess, I would say 34 units.
