Answer:
Step-by-step explanation:
we know that
If CD is parallel to XZ
then
Triangle XYZ is similar to Triangle YCD
therefore
The ratio of their corresponding sides are equal
we have
CX=5\ units, CY=25\ units, YD=20\ units,
substitute the values
Answer:
<h2><u><em>
36 - x</em></u></h2>
Step-by-step explanation:
a women buys 3 dozen eggs. Later ,she discovers that x of them are broken. How many eggs are not broken
3 * 12 - x =
36 - x
Answer:
k = 5
Step-by-step explanation:
Given y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 20 when x = 4, then
20 = 4k ( divide both sides by 4 )
5 = k
A right-angled triangle obeyes the Pythagoras theorem. This theorem states that the square of the longest side is equal to the sum of the square of the other two sides
so we will run this test on the triangle in the question
Longest side = 7
other sides = 2.5 and 6
Answer:
8x2y - 6x2 - 8xy2 - y2
Step-by-step explanation:
Equation at the end of step 1 :
(((((5•(x2))•y)-(5•(x2)))+(3y•(x2)))-(3•(y2)))-((((x2)+(y2))+(8x•(y2)))-3y2)
Step 2 :
Equation at the end of step 2 :
(((((5•(x2))•y)-(5•(x2)))+(3y•(x2)))-(3•(y2)))-((((x2)+(y2))+23xy2)-3y2)
Step 3 :
Equation at the end of step 3 :
(((((5•(x2))•y)-(5•(x2)))+(3y•(x2)))-3y2)-(x2+8xy2-2y2)
Step 4 :
Equation at the end of step 4 :
(((((5•(x2))•y)-(5•(x2)))+3x2y)-3y2)-(x2+8xy2-2y2)
Step 5 :
Equation at the end of step 5 :
(((((5•(x2))•y)-5x2)+3x2y)-3y2)-(x2+8xy2-2y2)
Step 6 :
Equation at the end of step 6 :
((((5x2•y)-5x2)+3x2y)-3y2)-(x2+8xy2-2y2)
Step 7 :
Final result :
8x2y - 6x2 - 8xy2 - y2
