Answer:
DE = 5
BC = 10
Step-by-step explanation:
ΔAED is a right triangle with legs of 4 and 6/2 = 3
Use the Pythagorean theorem to find DE
16 + 6 = 25 = 
DE = 5
The midsegment of a triangle is 1/2 the length of the corresponding side.
Therefore, BC = 2 DE = 2(5) = 10 = BC
Answer:
f(a) = 1,5
Step-by-step explanation:
-3a + 6b = a + 4b
[+3a] [+3a]
6b = 3a + 4b
[-4b] [-4b]
2b = 3a
[÷2] [÷2]
b = 1,5a
Answer:
0 real solutions
Step-by-step explanation:
This problem can be solved by simply looking at the sign in front of 89. Since it is a negative, nothing squared can equal it.
In other words, when a number is squared, the product will never be negative. This is because even when two negatives are multiplied by each other, the negatives cancel each other out.
Examples:
2^2 = 4
-2^2 = 4 (not -4)
