Answer:
(b) 3x^2 +6x+4
Step-by-step explanation:
(6x+7+x^2)+(2x^2-3)
= (1 +2)x^2 +(6)x +(7 -3) . . . . combine like terms
= 3x^2 +6x +4
The result can be shown in both exact and decimal forms.
Exact Form:
2
3
Decimal Form:
0.

6
Note that:
I = 1, V = 5, X = 10, L = 50, C = 100
XX = 20, II = 2
20 + 2 = 22
XXII = 22
Find the number on the next page (pg.23)
23 = XXIII
XXIII is your answer

Answer:
r = 1/2(s -t/x)
Step-by-step explanation:

We proceed as follows;
s = 2r + t/x
s - t/x = 2r
Divide both sides by 2
r = 1/2(s - t/x)
