The answer is B
Step-by-step explanation:
As shown in the given figure, ΔDEF is a right-angles triangle, where ∠DFE = 90°, DF = 15 units and EF = 20 units.
We are to find the length of DE.
ΔDEF is right-angled at ∠DFE.
So, using Pythagoras theorem, we have
\begin{lgathered}DE^2=DF^2+EF^2\\\\\Rightarrow DE^2=15^2+20^2\\\\\Rightarrow DE^2=225+400\\\\\Rightarrow DE^2=625\\\\\Rightarrow DE^2=25^2\\\\\Rightarrow DE=25.\end{lgathered}

Hello from MrBillDoesMath!
Answer:
Parabola
Discussion:
The equation is x = (1/16) y^2. Multiply both sides by 16 to get
y^2 = 16x is a parabola that "opens to the right". (Looks like y = x^2 rotated clockwise 90 degrees)
Thank you,

Answer:
The calculation for annual premium is explained below:
Step-by-step explanation:
Here we are given as:
DRF = 1.75
time period = 6 month = 2 times a year
basic rate = 750
Her annual premium will be: 
= 2625
Hence Wanda's annual premium will be 2625.
The answer is to isolte the unknown on one side by itself so
I hope you know how number lines because It is hard to do on branly so
1.
h-16 <u><</u>-24
add 16 to both sides
h<u><</u>8
graph
2. y+6 <u>></u>-13
subtract 6
y<u>></u>-19
graph
3. -3<n-8
add 8 to both sides
5<n
graph
4. 3<u><</u>m+1.4
subtract 1.4 from both sides
1.6<u><</u>m
graph
5. x+0.7>-0.3
subtract 0.7 from both sides
x>-1

6. w-8<u>></u>5.6
add 8 to both sides
w<u>></u>13.6
