Answer:
the first number in this sequence is 6....
Step-by-step explanation:
First number = x
2nd number = x+2
3rd consecutive even number = x+4
4th consecutive even number = x+6
Therefore,
By adding these numbers:
x+x+2+x+4+x+6= 36
Add the like terms:
4x+12=36
Combine the constants:
4x=36-12
4x=24
Divide both the terms by 4
4x/4 = 24/4
x= 6
Thus the first number in this sequence is 6....
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).
in the picture will explain the explanation
B.
as a, none is longer than 11 inches
b, 2 are longer than 11 inches
c, 3 have 9 inches (which is the shortest)
s, one has 9 inches
Answer:
area of square=36m²
area of square= side²
36cm²=side²
(36cm²)½=side
6cm=side
perimeter of square=4×side
perimeter of square =4×6cm
perimeter of square =24cm
