Answer:
132ft
Step-by-step explanation:
Mathius Distance = 3/8 mile
Eva Distance = 2/5 mile
1 mile = 5,280ft
1. Start by multiplying the mile distance of Mathius to the distance of 1 mile in feet.
5,280ft x 3/8 = 15840ft/8 = 1980ft
2. Do the same thing as number 1 but for Eva's distance now.
5,280ft x 2/5 = 10560ft/5 = 2112ft
3. Subtract Eva's Distance from Mathius' Distance for the answer.
2112ft (Eva) - 1980ft (Mathius) = <em>132ft</em>
If you would like to solve (x^2 + 5x - 36) / (x + 9), you can do this using the following steps:
a = ?
(x + 9) * (x + a) = <span>(x^2 + 5x - 36)
x^2 + ax + 9x + 9a = x^2 + 5x - 36
ax + 9x = 5x
a + 9 = 5
a = 5 - 9
a = - 4
The correct result would be x - 4.

Answer:
DE = 21
Step-by-step explanation:
Recall: the ratio of the corresponding side lengths of similar triangles are equal
Given that ∆ABC ~ ∆DEF, therefore,
AB/DE = BC/EF = AC/DF
AB = 8.4
DE = x
BC = 10
EF = 25
AC = 16.5
DF = 41.25
Let's find DE using AB/DE = BC/EF. Thus:
8.4/x = 10/25
Cross multiply
x*10 = 25*8.4
10x = 210
Divide both sides by 10
x = 210/10
x = 21
DE = x = 21
I think the answer is A not sure tho sorry if it’s wrong :(
