The 24 cubes would weigh exactly 6 pounds.
Step-by-step explanation:
Select all of the following that are quadratic equations.
x² + 3x - 5 = 0 ✓
x² - x = 3x + 7 ✓
5x - 7 = 0 X
7x² + 14x = 0 ✓
x³ - 3x² + 1 = 0 X
x - 5 = 9x + 7 X
What is quadratic equations?
Quadratic equations is a equation that has a general form like "ax² + bx = c"
For example :
x² + 3x - 5 = 0
x² + 3x = 5
x² → ax²
3x → bx
5 → c
Answer:
The numbers will be "11 and 12".
i believe
Step-by-step explanation:
x(x + 1) > x + x + 1 + 109 where x and x+1 are the 2 numbers.
x^2 + x > 2x + 110
x^2 - x - 110 > 0
(x - 11)(x + 10) > 0 The critical values are 11 and -10 but number must be natural
So the value of x is 11
The numbers are 11 and 12
Answer:
Step-by-step explanation:
Use the sum-product pattern
Common factor from the two pairs
Rewrite in factored form
We have y - 2 = m(x + 5), where m = (-1 - 2)/(10 + 5) = -3/15 = -1/5;
Then y - 2 = (-1/5)(x + 5);
5y - 10 = (-1)(x + 5);
5y - 10 = -x - 5;
x + 5y - 5 = 0 is the equation of the line.
