The equation can be written as (2x-3)^2
Ans since it is square, then we can take the root of the equation to find on side of the square, which is (2x-3) and by multiplying it by4, we can find the perimeter.

Solve for x…..…………………
anzhelika [568]

Answer:

x = 11

Step-by-step explanation:

From the diagram, we find,

(2x - 16) + (x - 8) = 9

=> 2x - 16 + x - 8 = 9

=> 2x + x - 16 - 8 = 9

=> 3x - 24 = 9

=> 3x = 9 + 24

=> 3x = 33

=> x = 33/3

=> x = 11

Quadrilateral ABCD is reflected over line y as shown, resulting in quadrilateral TURS. If AD 5 in., AB = 7 in., DC = 4 in., and
inn [45]



Answer:  7 inches.

Given that there was a quadrilateral ABCD and it was reflected over a line y

Hence preimage = ABCD and image = TURS

When reflected we have new position of A = T

new position of B =U

new position of C = R and

new position of D = S

By transformation properties, for reflection the scale factor is 1 and hence AB will have the same length as TU

Since AB = 7 inches, TU = 7 inches.

Note:

A reflection in the coordinate plane is just like a reflection in a mirror. Any point or shape can be reflected across the x-axis, the y-axis, or any other line, invisible or visible. This line, about which the object is reflected, is called the “line of symmetry.”  Here we have line of symmetry as line y.
