Answer:
20 ........................
The greatest whole number that number that rounds to 621,860 is 621,864
Answer:
Length = 34
Step-by-step explanation:
Perimeter of rectangle = a+a+b+b = 2(a+b)
Let a = length = 2b - 4
Let b = width
Therefore
(2b-4) + (2b-4) + b + b = 106 cm
Bracket off
2b-4+2b-4+b+b = 106cm
Collect like terms
2b+2b+b+b-4-4 = 106cm
6b-8 = 106
6b = 106+8
6b = 114
b = 114÷6
b = 19
To get a
2b - 4
2(19) - 4
38-4
= 34
X is equall to 9. Very simple, just look carefully.
<span> G(f(x)) = 2(x^2 -1) + 3
= 2x^2 + 1
subsitute 2
= 9
Hence, the answer is 9</span>
