Answer:
Given the information in the diagram, the measurement of <em>d </em> is 5m.
Step-by-step explanation:
In the diagram, we know that the two triangles are similar to each other meaning their segments have equal ratios. We are already given the measurements of two segments. Let's find the ratio.
8 : 4
This can also be written as...
2 : 1
Now, we can find the measurement of <em>d </em>by using this ratio.
Cross - multiply.
= 5
So, the measurement of <em>d </em> is 5m.

Answer:
Approximately 3.5 feet - Option B
Step-by-step explanation:
Imagine that you have this walkway around the garden, with dimensions 30 by 20 feet. This walkway has a difference of x feet between it's length, and say the dimension 30 feet. In fact it has a difference of x along both dimensions - on either ends. Therefore, the increases length and width should be 30 + 2x, and 20 + 2x, which is with respect to an increases area of 1,000 square feet.
( 30 + 2x ) ( 20 + 2x ) = 1000 - Expand "( 30 + 2x )
( 20 + 2x )"
600 + 100x + 4 = 1000 - Subtract 1000 on either side, making on side = 0
4 + 100x - 400 = 0 - Take the "quadratic equation formula"
( Quadratic Equation is as follows ) - ,
,
There can't be a negative width of the walkway, hence our solution should be ( in exact terms ) . The approximated value however is 3.5081...or approximately 3.5 feet.
