$12 each. $75 - $39 = $36. $36 divided by 3 = $12. Assuming he used all his money.
Answer:
Infinitely many
Step-by-step explanation:
12x + 1 = 3(4x + 1) - 2
12x + 1 = 12x + 3 - 2
12x + 1 = 12x + 1
Both sides are equal for all x, so infinite solutions
It's false. It's a product so...
Derivative of the first TIMES the second PLUS derivative of second TIMES the first.
Derivative of the first (x^3) = 3x^2
Times the second = 3x^2 * e^x
Derivative of the second = e^x (remains unchanged)
Times the first = e^x * x^3
So the answer would be (3x^2)(e^x) + (e^x)(x^3)
which can be factorised to form x^2·e^x(3 + x)
Answer:
Region covered by the dominoes is 90 unit²
Step-by-step explanation:
Here we have;
Area half of each domino = 1 unit²
Therefore, area of each domino = 2 unit²
Region where dominoes can be found = 8 × 6 dominoes
Region where dominoes can be found = 48 dominoes area unit²
Number of dominoes omitted = 3 dominoes
Therefore, total number of dominoes in region = 48 - 3 = 45 dominoes
Region covered by the dominoes = 45 × 2 unit² = 90 unit².
