Are 6 and 15 the legs of the triangle?
Answer:
x^ (5/3) y ^ 1/3
Step-by-step explanation:
Rewriting as exponents
(x^5y) ^ 1/3
We know that a^ b^c = a^(b*c)
x^ (5/3) y ^ 1/3
Answer: 3/2
Step-by-step explanation:
Since, two variables are called proportional if there is always a constant ratio between them.
And, The constant is called the coefficient of proportionality or proportionality constant.
Let x and y are proportional to each other.
Therefore, x ∝ y ⇒ y=kx
Where k is any constant.
For, x=2 and y=3 k= 3/2
For, x=4 and y=6, k=3/2
For x=6 and y=9, k= 3/2
Since, here the value of k is constant.
Therefore, k is the coefficient of proportionality.
And, given table is propositional.
3x^2 + 4x - 21x - 28
x(3x + 4) - 7(3x + 4)
(3x + 4) (x - 7)
Answer: B).
Answer:
71°
Step-by-step explanation:
- 84+(2x-1)+(x+8)+(x+5)=360 [angles in a quadrilateral add to 360°]
- 4x+96=360 [combine like terms]
- 4x=264 [subtract 96 from both sides]
- x=66 [divide both sides by 4]
So, angle A measures 66+5=71°
