Pulling out like terms
3.1 Pull out like factors :
-12e2 - 267e - 4 = -1 • (12e2 + 267e + 4)
Trying to factor by splitting the middle term
3.2 Factoring 12e2 + 267e + 4
The first term is, 12e2 its coefficient is 12 .
The middle term is, +267e its coefficient is 267 .
The last term, "the constant", is +4
Step-1 : Multiply the coefficient of the first term by the constant 12 • 4 = 48
Step-2 : Find two factors of 48 whose sum equals the coefficient of the middle term, which is 267 .
Step-by-step explanation:
Number of students who secured first class in English only is 20
Step-by-step explanation:
- Step 1: Find the number of students who secured first class in English only.
Total number of students who secured first class in English or Maths, T = 80
Number of students who secured first class in Maths, M = 50
Number of students who secured first class in both English and Maths, EM = 10
⇒ Let the number of students who secured first class in English only be x.
Total students with first class, T = M + EM + x
⇒ 80 = 50 + 10 + x
⇒ 80 = 60 + x
∴ x = 80 - 60 = 20
Answer:
The cost increase for each square of carpet by 12.
Step-by-step explanation:
The given function is
It is a slope intercept form of the line
Where m is the slope and b is y-intercept.
Therefore the slope of given function is 12 and the y-intercept is 50.
It means the initial ot fixed cost of the carpet is 50 and the cost increased by 12 for each square of carpet.
A....... The mean can't be 30 because normally, the mean is lower than the highest number in your data....
B.......... There are 5 numbers, and 15 is the 2nd highest number..... so no it can't be the median
His investment will reach 14,100 after 47 quarters or 11 years and 9 months
