Answer:
7w - 2
Step-by-step explanation:
you are subtracting w from 8w. Whenever there is a variable with no number beside it, it is an understood 1. so subtract 8w - 1w. This gives you 7w. then you move to the numbers with no variables. The 6 has a subtraction sign infront of it, which can be used as a negative sign. so -6 + 4 would be 2. therefore in whole, the answer would be 7w - 2. I do believe I am correct, but feel free to Comment if something should be corrected.
Answer:
If D = 0, then the quadratic equation has 1 solution x = − b/2a
Step-by-step explanation:
If we have a quadratic equation x² +3x-4= 0
Then the corresponding values of a= 1, b=3, c= -4
Finding the discriminant gives
D= b2 - 4ac.
D= 3²- 4(1) (-4)
D= 9 + 16
D= 25
Here a> 0
But if a< 0 e.g a= -1
D= b2 - 4ac.
D= 3²- 4(-1) (-4)
D= 9 - 16
D= -7
Here a < 0 so we get the answer -7 < 0
D= b2 - 4ac.
D= 4²- 4(-1) (-4)
D= 16 - 16
D= 0
Here a< 0 and b= - c so that D= 0
When D < 0 roots do not exist.
If D = 0, then the quadratic equation has 1 solution x = − b/2a
This can be found out by using the quadratic formula
x= -b±√b²- 4ac/ 2a
But D= 0
x= -b±0/ 2a
x= -b/2a
Answer:
Step-by-step explanation:
In order to solve this exercise it is important to remember that the "Repeated addition" is about adding equal groups of numbers.
Therefore, you can solve a mulitplication using the Repeated addition by repeat the same number "n" times in order to find the result..
In this case, you have the following multiplication given in the exercise:
You can observe that the number 34 is multiplied by 4. This indicates that the result is four times 34.
Then, based on the explained at the beginning of this explanation, you can conclude that you can also solve the given multiplication by repeating the number 34 four times and then adding the groups.
Therefore, you get:
