(x² - 3x + 2) - (3x² - 5x - 1)

This problem can be split up into like terms. So, all of the terms containing x² would be put together, the terms containing just one x would be put together, and the terms without x's would be put together.

(x² - 3x²) = -2x²

(-3x -  -5x)   Simplify the double negative
(-3x + 5x) = 2x

(2 - -1)   Simplify the double negative
(2 + 1) = 3

So, when you put those all together you get -2x² + 2x + 3.

Solve for x
mr Goodwill [35]

Answer:

Option (2). x = 20°

Step-by-step explanation:

In the figure attached,

ΔABC is an equilateral triangle.

By the property of equilateral triangle, all sides of the triangle are equal and measure of all angles of the triangle is 60°.

By this property,

m∠B = 60°

and y = 46 - 16 = 30

By applying Sine rule in ΔBCD,

\frac{\text{sin}60}{BD}=\frac{\text{sin}80}{46}=\frac{\text{sin}(\angle CBD)}{DC}

\frac{\text{sin}80}{46}=\frac{\text{sin}(\angle CBD)}{y}

sin(∠CBD) = \frac{30\times \text{sin}80}{46}

                 = 0.6423

m∠CBD = 39.96

              ≈ 40°

m∠ABD = 60° - 40°

             = 20°

Therefore, Option (2). 20° will be the answer.

Heeelllllpppp due Monday I give I suck at math??
Papessa [141]

Answer:

13.125

Step-by-step explanation:

Since the triangles are congruent, you would get the equation 4z-7=11z-112.

Then, you would subtract 4z from each side, leaving behing -7=8z-112. Then, you would add 112 to each side, getting 105=8z. Divide both sides by 8, and your answer is z=13.125
