You must graph the two given lines and find their point of intersection.  It is (10,5).  Shade the areas BELOW each of the 2 lines.  One line intersects the y-axis  at (0,15) and the other line intersects the x-axis at (12.5,0)
Thus, you have an area defined by the vertices given above.  

What to do next?  Steal the coordinates of each point and subst. them into the given objective function P = 15x + 20y.  For exampel, for (12.5,0), the value of P is 15(12.5) + 20(0) = 187.5.

Find P for each of the remaining 3 vertices.

The largest value of P is the answer to this question.

Help please and thank you
gulaghasi [49]

Answer:

56

Step-by-step explanation:

Missing length = x + 21

Based on the Three Parallel Lines Theorem, we have:

x/21 = 20/12

Cross multiply

x*12 = 20*21

12x = 420

12x/12 = 420/12

x = 35

✅Missing length = x + 21

Plug in the value of x

= 35 + 21

= 56

Over [174]

Answer:

<u>She needs 40.4 feet of wood.</u>

Step-by-step explanation:

➾ She had 8 pieces of wood that are 6.2 feet each, so <u>total length of wood she had</u> = 8×6.2

= <u>49.6feet</u>.

➾She needs total 90feet. of wood and she had already 49.6 feet of wood.

So, now wood she needed = 90-49.6

= <u>40.4feet</u><u>.</u>
