Answer:
The distributive property of multiplication
Step-by-step explanation:
<u>explanation</u>:-
The distributive property of multiplication states that when a number is multiplied by the sum of two numbers, the first can be distributed to both of those numbers and multiplied by each of them separately,then adding the two products together for the same result as multiplying the first number by sum.
a(b+c) = a.b + a.c
so -2 ( -3+7) = -2(-3) + (-2)(7)
-8 = 6 -14
-8 = - 8
give data we will use distributive property of multiplication
Answer:
Pythagorean Theorem: c2 = a2 + b2
Find the area by adding the areas of the three triangles. The area of a right triangle is: A = ½bh
Two triangles are identical so you can just multiply the area of the first triangle by two: 2A1 = 2(½bh) = 2(½ab) = ab.
The total area of the trapezoid is : A1 + A2 = ab + ½c2
You multiply both sides by 2 to get rid of the ½: (a2 + 2ab + b2) = 2ab + c2
You subtract out the 2ab: a2 + b2 = c2.
Then what is left is the proof: a2 + b2 = c2
k = 12
cancel out the r on both sides
then divide -144 by -12.
you get 12.
Answer:
Step-by-step explanation:
The experimental probability is the chance of an event happening based on data, or rather the experiment results, and not on a theoretical calculation. In essence, a theoretical calculation can be described by the following formula:
However, the experimental probability can be described with the following formula:
The number of trials is the sum of the number of outcomes. In this case, the desired outcome is tails. Therefore, the experimental probability can be described using the following formula:
One can also rewrite the formula as the following. This is because the total is the sum of the number of the two outcomes:
Substitute,
Simplify,
Rewrite as a decimal:
Sorry i don’t understand how to do C but this is what i have and my work hope it helps :)
