Answer:
Tawanna should have used each common factor once.
Step-by-step explanation:
Tawanna is asked to find the GCF of each term in the expression 2 a b + 8 b.
Factors of 2ab: 1, 2, a, and b
Factors of 8b: 1, 2, 4, 8, and b
GCF: (1) (1) (2) (2) (b) (b)
GCF = Greatest common factor
She has calculated the GCF incorrectly as she should use each common factor once only. But she has taken all the common factors twice which is wrong.
Hence, the error in Tawanna’s solution is that "Tawanna should have used each common factor once.". Hence, the correct option is (c).
Answer:84
Step-by-step explanation:
27/2=13.5(radius)
area: pi*r*r=
pi*13.5*13.5=
572.55526
rounded, 572.56
circumference: 2*pi*r(which is basically diameter times pi)
27pi=84.823
rounded, 84.82
F(x)=2x-5
Insert the value of x which is x+1 ->
F(x+1)= 2(x+1)-5
Distribute ->
F(x+1)=2x+2-5
Then, add like terms->
F(x+1)=2x-3
Plot 7 on the y axis then go down 4 places and left 1 and keep repeating till u can’t plot any more then go back to the 7 on the y axis and go up 4 and right 1 unroll you can’t plot any more. Your line should be going down from left to right
