Answer:

I would first convert 2x + 3y = 1,470 into slope intercept form y = mx + b which is y = -2/3x + 490.

From the equation of a line y = -2/3x + 490 I would plot the y-intercept (0, 490) on the graph. Afterwards, I would look at the slope -2/3 which is can be read as rise over run. From the y-intercept plot move down two spots as rise is -2 then over 3 spots for run to plot second point on graph. Finally, connect the dots to form a line.

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.
