That would be x^2 + 2x + 3
Answer:
D) 24.5
Step-by-step explanation:
use the pythagorean theorem.

Plug in the values. 
a+ 625 = 1225
then solve for a by subtracting 625 from 1225 = 600
√600= 24.5
Picture graphs usually show amounts using...pictures! So if you looked
at the symbols, you can likely guess the amounts. It might show how many
students preferred hamburgers by using a hamburger to represent every 5
students. Just by quickly glancing at a picture graph, you can usually
tell which result is the greatest.
ANSWER
The approximate solution is

EXPLANATION
The point of intersection of the two lines is the solution of the linear systems represented by the graph.
From the graph we can determine that each box is 2 units.
From the graph, when we start at O and count two boxes to the right and half box down, we obtain the point of intersection of the two lines to be

Note that since each box is two units, half way between the boxes gives one unit.
