Answer:
11 and 12
Step-by-step explanation:
x(x+1)=132
x^2+x=132
x^2+x-132=0
(x-11)(x+12)=0
x = 11 or x = -12
when x=11 ,
x+1=12
11*12=132

Answer:
13x-9
Step-by-step explanation:
9×(x - 1)
9x - 9 +4x
collect like terms, 9x+4x=13x
Solution: The test score that the teacher should expect from a student who did not attend her course is 37.
<u>Explanation:</u>
The teacher's equation for the line of best fit is 
We know the equation for the line of the best fit is:
Where:
is slope of the equation. It represents the rate of change in y as one unit change in x.
is the intercept. It represents the expected mean value of y when all x=0.
Therefore, in the given teacher's equation, the slope is 0.7 and intercept is 37.
Here the intercept means the average score of student who who did not attend her course.
Therefore, the test score that the teacher should expect from a student who did not attend her course is 37.
Answer:
<u>The next two terms for the geometric sequence are - 108 and - 324.</u>
Step-by-step explanation:
1. Let's find the next two terms for the geometric sequence which first three terms are as follows:
- 4, 12, - 36.....
Aₓ = Aₓ₋₁ * 3 ; A₁ = - 4
A₁ = - 4
A₂ = A₁ * 3 = - 4 * 3 = - 12
A₃ = A₂ * 3 = - 12 * 3 = - 36
A₄ = A₃ * 3 = - 36 * 3 = - 108
A₅ = A₄ * 3 = - 108 * 3 = - 324
<u>The next two terms for the geometric sequence are - 108 and - 324.</u>
