Answer:
12√2.
Step-by-step explanation:
You can do this by the Pythagoras theorem:
20^2 = x^2 + (4sqrt7)^2 where x is the distance required.
x^2 = 20^2 - (4sqrt7)^2
= 400 - 112
= 288
x = √288
= √144 *√2
= 12√2.
Answer:
10.5 units squared
Step-by-step explanation:
just count the squares up or use the formula (a+b)/2 * h .
Not sure what "each square is worth means" sorry, if you clarify I can answer
Answer:
True
Step-by-step explanation:
AD=DC (S)
Angle BAD = Angle BCD (A)
BD is similar side (S)
Therefore it is true because of SAS.
Y=mx+b
14=1(-4)+18
This could be an example of an equation in slope intersect form, where y=14 and x=-4
X>-6 is what i believe the answer is.
hope this helps!
