In most linear programming problems, there are two stages:

Answer: Bruno = 16 cans, Blaze = 14 cans

<u>Step-by-step explanation:</u>

Part A gave you the three equations.

Part B showed you the intersected points --> (16, 14), (20, 10), & (21.4, 10.7)

Part C is giving you the Cost function: C(x, y) =0.10x + 0.20y

Input the intersected points into the Cost function to find the maximum.

C(16,14) = 0.10(16) + 0.20(14)

= 1.60 + 2.80

= 4.40

C(20,10) = 0.10(20) + 0.20(10)

= 2.0 + 2.00

= 4.00

C(21.4,10.7) = 0.10(21.4) + 0.20(10.7)

= 2.14 + 2.14

= 4.28

Of the three results we just found, 4.40 is the biggest value.

So, the maximum occurs at C(16,14) = 4.40

Solve please its a test. Best answer gets brainliest

aniked [119]

Answer:

Step-by-step explanation:

Area of one triangle = 6*16/2 = 48 cm²

Lateral Surface Area = Are of 4 traiangles = 4*48 = 192 cm²

Area of the bottom square = 6 * 6 = 36 cm²

Total Surface Area = 192 + 36 = 228 cm²

What equation results from completing the squre and then factoring x^2+10=15

nlexa [21]

For this case we must complete squares:

$x ^ 2 + 10x = 15$

We add the square of half the coefficient of the term "x",

$(\frac {b} {2a}) ^ 2$ on both sides of the equation:

$x^2+10x+(\frac {10} {2 (1)}) ^ 2 = 25 + 15\\x ^ 2 + 10x + 5 ^ 2 = 25 + 15$

According to the perfect square trinomial we have:

$(a + b) ^ 2 = a ^2 + 2ab + b ^ 2$

Rewriting the expression we have:

$a = x\\b = 5\\(x + 5) ^ 2 = 25 + 15\\(x + 5) ^ 2 = 40$

ANswer:

$(x + 5) ^ 2 = 40$
