Help me pls!!!!!!!!!

Alexeev081 [22]

Answer:

93

Step-by-step explanation:

Line EJ is a straight line, with Line DC cutting through it. So 180 = Angle DCJ + Angle DCE. So Angle DCE = 48. Triangles are equal to 180°. So 180 = ? +39 +48. So ? = 93

If some one could help me with these three questions I will be stoked!!!please please help me my teacher didn’t walk us through

17) replace the given number for "x" and evaluate

a) x² + 2x + 1 ; when x = 3

3² + 2(3) + 1

= 9 + 6 + 1

= 16

b) x² + 2x + 1 ; when x = -4

(-4)² + 2(-4) + 1

= 16 - 8 + 1

= 9

c) x² + 2x + 1 ; when x = 3

(-22.872)² + 2(-22.872) + 1

= 523.128384 - 45.744 + 1

= 478.384384

18) The dependent variable is affected by the other variable and is the "output" The independent variable is the input.

a) y = 3x - 5; "x" is the independent variable

b) the time of day is the independent variable (you would input the time of day to calculate the temperature).

19) Let the x-axis represent the length of the lumber cut off and the y-axis represent the length of the lumber remaining.

To rationalize the denominator of 2/square 13+ squared 11 , you should multiply the expression by which fraction?

eimsori [14]

<u><em>Answer:</em></u>

You should multiply the expression by $\frac{\sqrt{13}-\sqrt{11}}{\sqrt{13}-\sqrt{11}}$

<u><em>Explanation:</em></u>

To rationalize any expression, you must multiply it by its conjugate. A conjugate is defined as a similar expression to the original one but with an opposite sign

<u>This means that:</u>

The conjugate of a + b would be a - b

Now, the given expression is $\frac{2}{\sqrt{13}+\sqrt{11}}$

<u>Consider the denominator:</u>

From the above, we can conclude that the conjugate of $\sqrt{13}+\sqrt{11}$ is $\sqrt{13}-\sqrt{11}$

<u>And, remember that</u> we need to keep the value of the expression unchanged. This means that we must multiply both the numerator and the denominator by the same value

<u>Therefore:</u>

You should multiply the expression by $\frac{\sqrt{13}-\sqrt{11}}{\sqrt{13}-\sqrt{11}}$ in order to rationalize the denominator

Hope this helps :)
