Answer:
93.5 in²
Step-by-step explanation:
To find the area, because this is a sheet of paper it is classified as a rectangle.
The formula for the area of a rectangle is a = lw
So a is what we are solving for or the area.
l = 11
w = 8.5
a = (11)(8.5)
The area of a sheet of printer paper is 93.5 in²
Answer:
m∠y=41
m∠x=90
Step-by-step explanation:
It is an isosceles triangle, so m∠B=49 too
49+49=98
180-98=82
82÷2=41
m∠y=41
41+49=90
180-90=90
m∠x=90
Answer : y = 3x + 2.
Explained : Distribute 3 to what’s inside of the parenthesis. Now you have y - 5 = 3x - 3. Add 5 to both sides and you have y = 3x + 2. Final answer.
Hi there!
There are four different types of transformations:
-Reflections
-Translations
-Rotations
-Dilations
In a reflection, the shape is simply reflected across a line of reflection. It does not change size or shape, so therefore it is a congruence transformation.
In a translation, the shape is moved up, down, left, or right. It does not change size or shape, so therefore it is a congruence transformation.
In a rotation, the shape is rotated around a point of rotation. It does not change size or shape, so therefore it is a congruence transformation.
In a dilation, the shape is made larger or smaller by a scale factor. It does change size, so therefore it is not a congruence transformation.
The transformation that is not a congruence transformation is a DILATION.
Hope this helps!! :)

Answer:
The value of x = 3.5 or -4
Step-by-step explanation:
=> 2x² = 28 – x
=> 2x²+ x - 28 = 0
=> 2x² + 8x - 7x - 28 = 0
=> 2x ( x + 4 ) - 7 ( x + 4 ) = 0
=> (2x - 7 ) ( x + 4 )
=> x = 7/2 = 3.5 or x = -4
