Rolling a 3 is 1/6
getting heads is 1/2
1/6 * 1/2 = 1/12 (odds of doing both)
Answer:
<em>x+y=4</em>
Step-by-step explanation:
hello :
note : by identity you have x²-y² = (x-y)(x+y)
in this exercice : 2x²-2y² = 2(x²-y²) = 2 (x-y)(x+y)
means : 2 (x-y)(x+y) = 40
but x-y = 5
so : 2(5)(x+y) =40
x+y=40/10
<em>x+y=4</em>
Answer:
(3u + 24) / (u + 9)
Step-by-step explanation:
6u + 72 / 2u + 24 ÷ u² + 21u + 108 / u² + 20u + 96
We'll begin by factorising u² + 21u + 108 and u² + 20u + 96. This can be obtained as follow:
u² + 21u + 108
Multiply u² and 108. The result is 108u². Find the factors of 108u² such that their sum will result to 21u. The factors are 12u and 9u.
u² + 12u + 9u + 108
u(u + 12) + 9(u + 12)
(u + 9)(u + 12)
u² + 20u + 96
Multiply u² and 96. The result is 96u². Find the factors of 96u² such that their sum will result to 20u. The factors are 12u and 8u.
u² + 12u + 8u + 96
u(u + 12) + 8(u + 12)
(u + 8)(u + 12)
6u + 72 / 2u + 24 ÷ u² + 21u + 108 / u² + 20u + 96 =
6u + 72 / 2u + 24 ÷ (u + 9)(u + 12) / (u + 8)(u + 12) =
(6u + 72) / (2u + 24) × (u + 8)(u + 12) / (u + 9)(u + 12)
(6u + 72)(u + 8)(u + 12) / (2u + 24)(u + 9)(u + 12) =
(6u + 72)(u + 8) / (2u + 24)(u + 9) =
6(u + 12)(u + 8) / 2(u + 12)(u + 9) =
6(u + 8) / 2(u + 9) = 3(u + 8) / (u + 9)
= (3u + 24) / (u + 9)
