Step-by-step explanation:
We are asked to simply (2√5 + 3√2)². Using formula: (a + b)² = a² + b² + 2ab. Let's say 2√5 = a, 3√2 = b. So,
→ (a + b)² = a² + b² + 2ab
→ (2√5 + 3√2)² = (2√5)² + (3√2)² + 2(2√5)(3√2)
We are aware about the fact that root means 1/2 and square of root means 2/2 that is 1. Using this we get:
→ (2√5 + 3√2)² = 4(5) + 9(2) + 2(2√5)(3√2)
Solve the brackets, to do so first put the like terms in one box.
→ (2√5 + 3√2)² = 4(5) + 9(2) + 2(2*3)(√5)(√2)
Solve the rest calculations.
→ (2√5 + 3√2)² = 20 + 18 + 2(6)(√10)
→ (2√5 + 3√2)² = 38 + 12√10
Option (a) (38 + 12√10) is the correct option.

Answer:
<u>Use a </u><u>table</u>
- The display will be used to look up individual values.
- It will be used to compare individual values but not entire series of values to one another.
- Precise values are required.
- The quantitative information to be communicated involves more than one unit of measure.
- Both summary and detail values are included.
<u>Use a graph</u>
- The message is contained in the shape of the values (e.g. patterns, trends, exceptions).
- The display will be used to reveal relationships among whole sets of values.

Answer:
x intercept is (4,0)
The y intercept is (0,12).
Step-by-step explanation:
Graph the x intercept (4,0) and the y intercept (0,12) and connect them with a line.
_______________________________________________________
(Equation) 3x + y = 12
To find the x intercept, set y = 0.
3x + 0 = 12
3 • 3 = 123
x = 4
The x intercept is (4,0).
To find the y intercept, set x = 0.
3(0) + y = 12
0 + y = 12
y = 12
The y intercept is (0,12).
To graph this line using the intercepts, first graph the two points (4,0) and (0,12). Then connect the two points with a line.
