Answer:
the answer is distributive property
Step-by-step explanation:
the distributive property tell us that the multiplication of a number (in this case number 3) by a sum (in this case x+y) is equal to the sum of the multiplications of that number by each of the terms belonging to the sum:
3(x+y)=3*x+3*y
3(x+y)=3x+3y
Answer: 5.25 or 5.5 [see note]
Step-by-step explanation:
1/4 (15 – 6) +3 <em><u>[I'm not clear what is meant by the " : 12," so I left it out.]</u></em>
1/4 (9) +3
9/4 + 3
2.25 + 3 = 5.25
===
If it is supposed to read
1/4 (15 – 6) +3/12
Then it would be
5.25 + 0.25 = 5.5
This is Pythagorean theorem.
We already know a and c.
a = 4 and c = 10
4² + b² = 10²
16 + b² = 100
Subtact 16 from each side.
b² = 84
Square root of each side:
b = ≈9.165 or √84
Hope this helps!
