Answer:

Step-by-step explanation:
The even number of minus signs means the product will be positive. A factor of 3 can be removed to simplify the product. As usual, the numerator of the product is the product of numerators, and the denominator of the product is the product of denominators.

Answer:
Step-by-step explanation:
If one event has p possible outcomes, and another event has m possible outcomes, then there are a total of p • m possible outcomes for the two events. Rolling two six-sided dice: Each die has 6 equally likely outcomes, so the sample space is 6 • 6 or 36 equally likely outcomes.
Answer:
17.5
Step-by-step explanation:
175% is written as 175/100. If you move the decimal at the end over twice you get 1.75/1 which is just 1.75. You then multiple 10 by 1.75 and you get 17.5

Correct option is C)
On putting x=2y+5 in second equation, we get
y=(4y+7)(2y+14)
⇒8y 2 +70y+98=y
⇒8y 2+69y+98=0
Discriminant D=69 2−4(8)(98)=1625>0
Hence, the equation has 2 real roots.
Therefore, there are 2 ordered pair.
Option C is correct.
