Answer:
The value of x could be 3
Step-by-step explanation:
2 x 3 = 6 + 1 - 4 = 3 which is less than 5
<u>Sum of Cubes:</u>
a³ + b³ = (a + b)(a² - ab + b²)
Example: x³ + 8 → a=x, b=2
= (x + 2)(x² - 2x + 4)
<u>Difference of Cubes:</u>
a³ - b³ = (a - b)(a² + ab + b²)
Example: x³ - 27 → a=x, b=3
= (x - 3)(x² + 3x + 9)
<u>Difference of Squares:</u>
a² - b² = (a - b)(a + b)
Example: x² - 16 → a=x, b=4
= (x - 4)(x + 4)
<span>3^3 ÷ 9 / 11 - 2^2
=27 </span>÷ 9 / 11 - 4
= 27 * 11/9 -4
= 297/9 - 4
=33-4
=29
You need to find 2 numbers x and y that solve the equations:
x * y = 35
x + y = 12
it looks like x = 5 and y = 7 will work
Answer:
1) -10
2) 1
Step-by-step explanation:
1) (-5) - 5
- Removing the brackets won't change anything since it is subtraction, so now it will be - 5-5 which is equal to -10.
-5 -5 = -10
2) (-10) + 11
- The same case applies here since it is addition.
-10 + 11 = 1
