Answer:
use the reverse Pythagorean therm BC= 4 DE= 4.8
Step-by-step explanation:
The square root of 5(squared) - 3(squared) = 4
the square root of 8(squared) - 6.4(squared) = 4.8
Answer:
BC = 25
Step-by-step explanation:
If the base angles are equal, then the sides opposite them are as well.
- 4x + 4 = 6x - 14 Subtract 4x from both sides
- 4x - 4x + 4 = 6x - 4x - 14 Combine
- 4 = 2x - 14 Add 14 to both sides
- 4 + 14 = 2x - 14 + 14 Combine
- 18 = 2x Divide by 2 and switch
- 2x/2 = 18/2 Combine
- x = 9
But that's not what you are asked for. You want the value of 2x + 7
- BC = 2x + 7
- BC = 2*9 + 7
- BC = 25
182 justo use a calculator xd
Answer:
25/36
Step-by-step explanation:
5/6 x5/6
=25/36
-9x - 9y = -30....divide everything by -3
3x + 3y = 10
as u can see, it is the exact same equation as the first equation. This means ur 2 lines are actually the same line. These are called coincident lines and they have infinite solutions.
