Answer:

(5x + 7y)² = 25x² + 70xy + 49y²

Step-by-step explanation:

(5x + 7y)² = 25x² + 70xy + 49y²

Because,

(5x + b)² = (5x)² + 2(5x)(b) + b²

2(5x)(b) = 70xy

b = 7y

b² = (7y)² = 49y²

True or face dilations preserve angle measure
Ilia_Sergeevich [38]

Answer:

True

Step-by-step explanation:

Required

Does dilation preserve angle measure?

When a point, side, line, or angle is dilated; the length of the line will be altered by the ratio or scale of dilation.

However, the measure of angle will remain the same.

<em>Hence, the given statement is true.</em>

A pair of parallel lines is cut by a transversal, as shown:
Hitman42 [59]

The correct answer is option C which is x = y.

<h3>What is the alternate interior angle?</h3>

The angle formed by the line intersecting two parallel lines is called the alternate interior angle. This two angles are equal in magnitude.

In the given figure we can see that the angle x will be equal to the angle y because of the right opposite angles.

Since two parallel lines are cutting the upper part at x so the same lower part will be also x due to corresponding angles.

Now just right opposite to x there is an angle y so the angles x and y will be equal to each other.

Therefore the correct answer is option C which is x = y.

To know more about alternate interior angles follow

1) Solve the equation 7x+5 = 7x-3
babymother [125]

Answer: no solutions

7x + 5 = 7x - 3

5 = -3                  [ subtract 7x from both sides ]

Since we end up with 5 = -3, a clearly false equation, we conclude that the original equation has no solutions.

i hope this helps! :D

HURRYYYY !!!!! The graph of f(x) = 2x is shown on the grid. The graph of g(x) = ()x is the graph of f(x) = 2x reflected over the
Tanya [424]

Reflecting through x=0 maps x to -x so

g(x) =f(-x) = -2x

Answer: y = -2x

Can't see the choices, look for a downward slope of two units down for every unit to the right, through the origin.
