<span>In abstract algebra and formal logic, the distributive property of binary operations generalizes the distributive law from elementary algebra. In propositional logic, distribution refers to two valid rules of replacement. The rules allow one to reformulate conjunctions and disjunctions within logical proofs.</span>

The distributive property generally refers to the distributive property of multiplication. This property lets you multiply a number by a sum by multiplying that number by each addend and then adding those products.

Ex. 5 ( 2+3+6 ) --> 5(2) + 5(3) + 5(6)
10 + 15 + 30 = 55

I don't even know how to figure this out. I don't have a formula for this

yuradex [85]

Answer:

$\sin\theta=\dfrac{15}{17}$

$?=15$

Step-by-step explanation:

Use the trigonometry formula

$\cos^2\theta+\sin^2\theta=1$

You are given that

$\cos \theta=\dfrac{8}{17}$

Substitute into the first formula

$\left(\dfrac{8}{17}\right)^2+\sin^2\theta=1\\ \\\dfrac{64}{289}+\sin^2\theta=1\\ \\\sin^2\theta=1-\dfrac{64}{289}=\dfrac{289-64}{289}=\dfrac{225}{289}\\ \\\sin \theta=\pm \dfrac{15}{17}$

Angle $\theta$ is acute angle, then the sine of this angle is positive and

$\sin\theta=\dfrac{15}{17}$

X/3/4 = 100<br> what does x equal

Crank

Answer:

x=1200

Step-by-step explanation:

x/3/4=100

Step 1: Multiply both sides by 4.

x/3/4=100

(x/3/4)*(4)=(100)*(4)

x/3=400

Step 2: Multiply both sides by 3.

3*(3/x)=(3)*(400)

x=1200

A triangle has sides with lengths of 4 inches, 14 inches, and 17 inches. Is it a right triangle?

irga5000 [103]

Yes it is because 2 sides would be the legs while 1 side is the hyptonuese so in this case 4 is a leg and 14 and 17 is the hyptonuese
