Hey there!

5x - 7x^2 - (2x)^2

= 5x - 7x^2 - 4x^2

COMBINE the LIKE TERMS

(5x) + (-7x ^2 - 4x^2)

= -7x^2 - 4x^2 + (5x)

= -11x^2 + 5x

Therefore, your answer is: -11x^2 + 5

Good luck on your assignment and enjoy your day!

Answer:

5x - 7 {x}^{2}  -  {(2x)}^{2}  \\  = ( {2}^{2}  {x}^{2} ) - 7 {x}^{2}  + 5x \\  = 4 {x}^{2}  - 7 {x}^{2}  + 5x \\  = x(4x - 7x + 5) \\  = x( 5 - 3x) \\  = { \underline{ \underline{ \:  \:  5x - 3 {x}^{2}  \:  \: }}}

Only the triangles in figures <u>5 are congruent</u>

<h3>Further explanation </h3>

Triangles are said to be congruent if:

  • 1. all three sides equal (SSS ---> side, side, side)
  • 2. two sides and the included angle of 2 triangles, are equal (SAS -> Side, Angle, Side)
  • 3. If the two angles and the included sides of the 2 triangles are equal (ASA -> Angle, Side, Angle)
  • 4. If the two angles and the non-included sides of 2 triangles are equal (AAS -> Angle, Angle, Side)

1. △ABC ≠ △DCE : not congruent

at least 3 parts (sides or angles) are compared, in the picture only 2 sides are compared

2. △ABC ≠ △XYZ : not congruent

the angles not includes between two sides

3. △RST ≠ △VUT : not congruent

a minimum of 3 parts (sides or angles) are compared, in the picture only 1 angle and 1 side are compared

4. △DEF ≠ △DHG :  not congruent

at least 3 parts (sides or angles) are compared, in the picture only 2 sides are compared

5. △JKL ≅ △KJM : congruent with ASA theorem

state the slope and y-intercept for the graph of the equation y=-3x+5state the slope and y-intercept for the graph of the equati
Alchen [17]
In Y=-3x+5 the slope is: -3 and the Y intercept is 5.

Explanation:
The equation without any actual inputs is: Y=mX+B. m refers to the slope. B is the Y intercept. So when looking at the equation with information inputted. You would follow the same structure. Slope will be with the X and Y intercept will be added after.
