Answer:

D. 3 and -4

Step-by-step explanation:

Given the expression, x² - x - 12, let's factorise to find the value of p and q using the table, for which we would have the expression simplified as (x + p)(x + q)

From the table, let's find the values of p and q that would give us -12 when multiplied together, and would also give us -1 when summed together.

Thus, from the table given, the row containing the values of p(3) and q(-4) gives us = -1 (p+q) . p = 3, q = -4 would be our values to use to factor x² - x - 12, as multiplying both will also give us "-12".

Thus, x² - x - 12 would be factorised or simplified as (x + 3)(x - 4)

Therefore, the answer is: D. 3 and -4

Evaluate the function<br> f(x)= 7.45x + 33.7 at x= -4.3

slavikrds [6]

First, you have to substitute for x, which would make the problem f(x)=7.45(-4.3)+33.7
Now, you just have to use the PEMDAS method (Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction)
f(x)= -32.035+33.7
f(x)=1.665

Convert the following measurements. Round your answers to two decimal places. a. 14,974 pounds to tons b. 8,047 ounces to pounds

Vikki [24]

For this case we have to know the following conversions:
$1 ton = 2204.62 pounds

1 oz = 0.0625 pounds$
Now we apply the conversions:

14,974 pounds to tons:
$(14974) * (1 / 2204.62) = 6.79 tons
$

8,047 ounces to pounds:
$(8047) * (0.0625) = 502.94 pounds
$

64 ounces to pounds:
$(64) * (0.0625) = 4 pounds
$

27 ton to pounds:
$(27) * (2204.62) = 59524.74 pounds$

A six-sided fair die and an eight-sided fair die are rolled together. What is the probability of getting numbers whose sum is a

aalyn [17]

There are 48 possible outcomes in this situation, and of those outcomes, the ones whose sums are a multiple of three are;
12, 21, 15, 51, 24, 42, 33, 18, 27, 36, 63, 45, 54, 48, 57, and 66. So, that is 16 out of 48 possibilities, or 16/48, which simplifies to 1/3. Written as a percent, the probability of getting numbers whose sum is a multiple of three is 33.33%.

Hope this is helpful! :)
