As you get older your brain develops as you do so when you’re taught math your brain is developing a slightly slower pace than it should be for example if you have a teacher who doesn’t really teach a lot it’s really going to slow down the process of learning
The reason that justifies why Rachel stated that m∠4 + m∠5 + m∠6 = 180° is: A. Triangle sum theorem
<h3>What is the Triangle Sum Theorem?</h3>
The triangle sum theorem states that for any given triangle, the sum of all its interior angles will be equal to 180°.
Thus, given the diagram showing a triangle, where ∠4, ∠5, and ∠6 are supplementary angles to the interior angles ∠1, ∠2, and ∠3 of the triangle.
Since all interior angles add up to 180°, the sum of their supplements, ∠4, ∠5, and ∠6 will also be 180°.
Therefore, the reason that justifies why Rachel stated that m∠4 + m∠5 + m∠6 = 180° is: A. Triangle sum theorem

Explanation:
If line segments PQ has endpoints at P(-5, 4) and Q(7, -5).
To determine the length of the line, we use the distance formula:
![\begin{gathered} Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\ \text{Where:} \\ $$\mleft(x_1,y_1\mright)=P\mleft(-5,4\mright)$$ \\ (x_2,y_2)=Q\mleft(7,-5\mright). \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20Distance%3D%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D%20%5C%5C%20%5Ctext%7BWhere%3A%7D%20%5C%5C%20%24%24%5Cmleft%28x_1%2Cy_1%5Cmright%29%3DP%5Cmleft%28-5%2C4%5Cmright%29%24%24%20%5C%5C%20%28x_2%2Cy_2%29%3DQ%5Cmleft%287%2C-5%5Cmright%29.%20%5Cend%7Bgathered%7D)
Substituting the given values, we have:
Answer:
D
Step-by-step explanation:
to find the value in grams, we just multiply by a 1000
so, 31.8 × 1000 = 31,800 grams
[-2] - [4-15]
= [-2] - [-11]
= -2 + 11 = 9
