Answer:

x = ± 7

Step-by-step explanation:

Given

(2x - 1)(3x + 2) = x + 292 ← expand left side using FOIL

6x² + x - 2 = x + 292 ( subtract x from both sides )

6x² - 2 = 292 ( add 2 to both sides )

6x² = 294 ( divide both sides by 6 )

x² = 49 ( take the square root of both sides )

x = ± 7

That is x = - 7, x = 7

Answer:

The system  that represent the scenario is

x+y\leq500

215x+615y\leq 187,500

The solution in the attached figure

Step-by-step explanation:

Let

x-----> the acres of corn

y----> the acres of cotton

we know that

x+y\leq500 ------> inequality A

215x+615y\leq 187,500 -----> inequality B

using a graphing tool

15 Points!! Is this my teacher's fault? The math and the picture aren't making sense. The blue is my answer.
kogti [31]

Answer:

Your teacher is correct.

Step-by-step explanation:

So first we would have to find what A is equivalent to which is 48. This is because 180 - 132 = 48. Since we know that 132 is a supplementary angle, there has to be another supplementary angle that results in the sum of 180.

With this information in mind, we can create the expression:

2x + 4x + 48 = 180 (A triangle is equal to 180 degrees)

Now simply the equation:

6x + 48 = 180

6x = 132

6x/6 = 132/6

x = 22

Angle C = 44

Angle B = 88
