A and C are the correct answers.
I hope this helps.
Answer:
8(x-10)
Step-by-step explanation:
When the calculation is repetitive, I like to let a calculator or spreadsheet do it. The value of the given function is
4·20 -10 = 70
Only the expression 8(x-10) = 8(20-10) = 80 has a larger value for x=20.

Answer:
P(B)=0.30
Step-by-step explanation:
Out of 1000 Voters, 30% favor Jones.
Event S=Favors Jones on First Trial
Event B=S occurs on Second Trial
P(S)=0.30
P(S')=1-0.30=0.70
Event B could occur in two ways
Therefore,
P(B)=P(SS)+P(S'S)
=(0.3X0.3)+(0.7X0.3)
=0.09+0.21
=0.3
Therefore, the probability of event B(that event S occurs on the second trial), P(B)=0.30.
The equation becomes 4610 = 2115, which is not true.
Let's break down the given equation and the steps to solve it step by step:
Given the equation: 47 × 98
Step 1: Express 98 as a combination of (47)'s and (2)'s. (98) can be written as (47 × 2).
Step 2: Substitute the expression for 98 in terms of 47 and 2 back into the equation:
47 × 98 = (47 × 47) - (2 × 47)
Step 3: Calculate the values on both sides of the equation.
- The left side: 47 × 98 = 4610.
- The right side:
- 47 × 47 = 2209
- 2 × 47 = 94
- Subtracting 94 from 2209 gives 2115.
Explanation:
1. We start with the equation 47 × 98, where 98 is represented as 47 × 2.
2. We substitute 98 in terms of 47 and 2 to get (47 × 47) - (2 × 47).
3. We calculate the values on both sides of the equation to find that they don't match. This indicates that the original equation is not true.

Answer:
The answer to your question is:
2 and -49
Step-by-step explanation:
2 x -49 = -98
2 + (-49) = -47
x2 - 47x - 98 = 0
The solution to factor the quadratic equation above is:
(X + 2 ) (X - 49)
Since 2 and -49 multiply to -98 and add up -47, you know that the following is true:
x2 - 47x - 98 = (X + 2 ) (X - 49)
Answer:
122 Degrees
Step-by-step explanation:
Since we are given that angle 1 and 2 make a linear pair:
angle 1 + angle 2 = 180 degrees ----------------------------(1)
We have also been told that angle 2 is 6 more than twice the measure of angle 1
Which means: angle 2 = (2*angle1) + 6 -------------------(2)
From putting the value of angle 2 in (1) from (2)
angle 1 + 2*angle 1 + 6 = 180
3*angle 1 = 174
angle 1 = 58 degrees -----------------------(3)
From (1) and (3):
angle 2 + 58 = 180
angle 2 = 122 degrees
Therefore, the measure of angle 2 is 122 degrees
