The parallel sides AB, PQ, and CD, gives similar triangles, ∆ABD ~ ∆PQD and ∆CDB ~ ∆PQB, from which we have;
<h3>Which method can be used to prove the given relation?</h3>
From the given information, we have;
According to the ratio of corresponding sides of similar triangles, we have;
Which gives;
QD × x = BD × z
BD × z = (1 - QD/BD) × y = y - (QD × y/BD)
Therefore;
BD × z = y - (QD × y/BD)
BQ × y = y - (QD × y/BD)
BQ × y = y - (z × y/x) = y × (1 - z/x)
(1 - z/x) = BQ
BD × z = y × (1 - z/x)
BD = (y × (1 - z/x))/z
Therefore;
QD × x = y × (1 - z/x)
(BD-BQ) × x = y × (1 - z/x)
(BD-(1 - z/x)) × x = y × (1 - z/x)
BD = (y × (1 - z/x))/x + (1 - z/x)
BQ + QD = (1 - z/x) + (y × (1 - z/x))/x
BD = BQ + QD
(y × (1 - z/x))/x + (1 - z/x) = (y × (1 - z/x))/z
(1 - z/x)×(y/x + 1) =(1 - z/x) × y/z
Dividing both sides by (1 - z/x) gives;
y/x + 1 = y/z
Dividing all through by y gives;
(y/x + 1)/y = (y/z)/y
Therefore;

Asking someone else to start from scratch and explain everything when you yourself have not done or shared anything is a BIG and unrealistic order.
Could you not at least share your thoughts as you read through each of the four problems?
Let's take a look at the 2nd problem (#17):
"Three times the sum of two times m and 5 is 4 less than 8 times m to the 2nd power." You must be able to translate a word problem like this one into algebraic symbols.
3(2m+5) = 8m^2 -4 (This is the desired answer)
Then 6m + 15 = 8m^2 - 4 => 8m^2 - 6m - 4 - 15 = 0 (after rearrangement)
Then 8m^2 - 6m - 19 (you are not required to solve this)
Please choose another problem from your list and do and share all you can about your efforts to solve it.
Answer:
-3 is just the answer of the equation.....you must solve x so turn it into 1x and solve it.....plz mark me brainliest

Answer:
5/6
Step-by-step explanation:
probability of rolling a 5 on a die=1/6
P of not rolling a 5 = 1-1/6= 5/6
