-13 -23 because divide by two then add five and subtract 5
Answer:
We have 252 different schedules.
Step-by-step explanation:
We know that as a freshman, suppose you had to take two of four lab science courses, one of two literature courses, two of three math courses, and one of seven physical education courses.
So from 4 lab science courses we choose 2:

So from 2 literature courses we choose 1:

So from 3 math courses we choose 2:

So from 7 physical education courses we choose 1:

We get: 6 · 2 · 3 · 7 = 252
We have 252 different schedules.
Answer:
x = −10 and x = 4
Step-by-step explanation:
x2 + 6x = 40
Subtract 40 from each side
x^2 + 6x -40 =0
Factor, what 2 numbers multiply to -40 and add to 6
10 * -4 = -40 10+-4 = 6
(x+10) (x-4) = 0
Using the zero product property
x+10 =0 x-4=0
x=-10 x=4
A squared plus b squared = c squared will help
Answer:
REAL NUMBER - real number is union of rational and irrational numbers .... whole numbers, natural numbers, integers, rational and irrational numbers are included in real numbers.
INTEGER -. integer means
means whole - valued positive or negative number or 0......
suppose 1, 2, 3, -6, -2....
whole numbers, such as 3, 4, but not 3.6 or √4 .
I hope you understand the difference between real numbers and integers.......
