Your answer will be option D.
Step-by-step explanation:
123 + x = 180
x = 180 -123
x = 57
Just do 8/4 = 2/y, should be correct.
Answer:
<h3>C.) The area of EFGH is always ¹/₂ of the area of the rectangle. </h3>
Step-by-step explanation:
If EG is parallel to the side of the rectangle then lenght of EG is equal to width of rectangle.
If F and H are midpoints of sides of rectangle then FH is parallel to the side of rectangle {wich is perpendicular to the side parallel to EG}. That means the lenght of FH is equal to lenght of rectangle, and FH is perpendicular to EG.
Then FH is sum of hights of triangles EFG and EHG , and the area of EFGH is sum of areas of triangles EFG and EHG .
So the area of the rectangle:
The area of the kite:
No matter the height of the triangles, so no matter the location of the EG
Answer:
B
Step-by-step explanation:
<em>a/b × d/c = a×d / b×</em><em>c</em>
Multiply the numerators 1st.
x × x = x^2
Next is the Denominator.
x+3 × x+2
now try to multiply each term of the 1st expression with the 2nd.
x × x + x × 2 + 3 × x + 6
x^2 + 2x + 3x + 6
x^2 + 5x + 6
Write the numerator & denominator in their respective places.
x^2 / x^2 + 5x + 6
