Answer:

The answer is "789.03 and 806.16".

Step-by-step explanation:

$y\^ \ \ = -0.45 + 3.78(x) -11.88(d_1) + 5.25(d_2)$

For point a:

Calculating the value for $y\^ \ \ x = 212,\ \ d_1 = 1, and \ \ d_2 = 0$

$y\^ = -0.45 + 3.78(212) -11.88(1) + 5.25(0)$

$= -0.45 + 801.36 -11.88 + 0\\\\= 789.03$

For point b:

Calculating the value of $y\^ \ \ for \ \ x = 212, \ \ d_1 = 0, and \ \ d_2 = 1$

$y\^ = -0.45 + 3.78(212) -11.88(0) + 5.25(1)$

$= -0.45 + 801.36 -0 + 5.25\\\\= 806.16$

ludmilkaskok [199]

Answer and step-by-step explanation:

If it is a rectangle, the formula is:

L * W

Fill in the values:

4*6.9

Then solve.

27.6

So, if it is a rectangle, the answer is (C), 27.6 Inches squared.

If it is a triangle, the the formula is:

(B*H)/2

Fill in the values:

4*6.9/2

Simplify:

27.6/2

Then solve.

13.8

So, if it is a triangle, the answer is (A), 13.8 Inches squared
