Answer:

x = 3

Step-by-step explanation:

Combining the constants on the left side, we get 15x - 23 = 22.

Adding 23 to both sides isolates 15x: 15x = 22 + 23 = 45.

Finally, dividing both sides by 15 yields x = 3

Bad White [126]

Answer:

(a) The product of the sum of a and b and their difference.

$(a+b)\times{(a-b)}\\=a^2-b^2$

(b) The tripled product of 6a and b².

$3(6a\times{b^2})\\=3(6ab^2)\\=18ab^2$

elena-s [515]

Answer:

9.847 %

Step-by-step explanation:

Be p1 the probability that the mammogram detect breast cancer in a woman.

p1=81%.

The probability 'P' that independent and consecutive 'n' singular events with p probability occur is:

$P=p_{1} ^{n}$

In this case:

P: Probability that breast cancer be detected on 11 women with breast cancer.

$P=0.81^{11}=0.09848$

$P=9.847$ %
