i dont if is right just tring yo help
Step-by-step explanation:





<u>Let us assume that:</u>

<u>Therefore, the equation becomes:</u>






<u>Now substitute the value of u. We get:</u>


<u>Therefore:</u>


★ <u>Which is our required answer.</u>

(a + b)² = a² + 2ab + b²
(a - b)² = a² - 2ab + b²
a² - b² = (a + b)(a - b)
(a + b)³ = a³ + 3ab(a + b) + b³
(a - b)³ = a³ - 3ab(a - b) - b³
a³ + b³ = (a + b)(a² - ab + b²)
a³ - b³ = (a - b)(a² + ab + b²)
(x + a)(x + b) = x² + (a + b)x + ab
(x + a)(x - b) = x² + (a - b)x - ab
(x - a)(x + b) = x² - (a - b)x - ab
(x - a)(x - b) = x² - (a + b)x + ab
The answer is 4.2 because you have to replace r with -14.1 and s with 18.3. After that you subtract them and you get 4.2
Answer:
26.0 in
Step-by-step explanation:
area = half base ×height
base=13÷2
=6.5
height=4
6.5×4
=26
Answer:
9/4
Step-by-step explanation:
We follow bodmas
4/3 +( -1/6 + 13/12)
( lcm = 12)
( -2+ 13/12)
( 11/ 12)
4/3 + ( 11/12)
4/3 + 11/12
lcm = 12 also
and that will equal to
=16 + 11/ 12
= 27/ 12
divide by 3 to simplest form
= 9/4
