If a, b, and c are prime numbers, do (a + b.and c have a common factor that is greater than 1 ?

valina [46]

Let's do the math. In the example a =2, b = 3, c = 5. If we are trying to see if the sum of these numbers has a common factor more than 1 do the math. 2 + 3 + 5 = 10. Ten has four factors which are 1, 2, 5, and 10. So the answer to your question is yes.

Find the radius of a circle with the given circumference. 12 in

vampirchik [111]

Step-by-step explanation:

Given 

circumference = 12 inch

π = 3.14

radius (r) = ?

We know 

circumference = 2πr 

12 = 2* 3.14 * r

r = 12 / 6.28

Therefore r = 1.91 inch

If sin(A+B)=1/2 & sin(A-B)=1/3 find sin(2A)

timofeeve [1]

Answer:

sin(2A) = (2√2 + √3) / 6

Step-by-step explanation:

2A = (A+B) + (A−B)

sin(2A) = sin((A+B) + (A−B))

Angle sum formula:

sin(2A) = sin(A+B) cos(A−B) + sin(A−B) cos(A+B)

sin(2A) = 1/2 cos(A−B) + 1/3 cos(A+B)

Pythagorean identity:

sin(2A) = 1/2 √[1 − sin²(A−B)] + 1/3 √[1 − sin²(A+B)]

sin(2A) = 1/2 √(1 − 1/9) + 1/3 √(1 − 1/4)

sin(2A) = 1/2 √(8/9) + 1/3 √(3/4)

sin(2A) = 1/3 √2 + 1/6 √3

sin(2A) = (2√2 + √3) / 6

Jeremy is building a large deck for a community center. The deck is shaped as a rectangle. The width of the deck is 29 feet. The

sasho [114]

A.
P=2(L+W)
W=29
P is at least (means greater than or equal than ) 134

so
134≤2(L+29) is the inequality

B.
solve
divide both sides by 2
67≤L+29
minus 29 from both sides
38≤L
Length is any value greater than or euqal to 38ft
