Hello from MrBillDoesMath!
Answer:
sqrt(105)
(which is approximately 10.25 centimeters
)
Discussion:
Call the unknown leg"a". From the Pythagorean theorem
8^2 + a^2 = 13^2 => subtract 8^2 = 64 from both sides
a^2 = 13^2 - 64 => as 13^2 = 169
a^2 = 169 - 64 = 105 => take the square root of both sides
a = sqrt(105) which is approximately 10.25 centimeters
Thank you,
MrB
Answer:20x+50= 5x+70
Step-by-step explanation:
x = number of cavities
use the subtraction property of equality and solve for x
20x+50 = 5x+70
-5x -50 -5x - 50
15x = 20
Then you divide 20 by 15
15x = 20
----- -----
15 15
x= 4/3
Make the equations equal and solve for x
- 2x²+6x+1=-4x²+1
- 6x²+6x=0
- 6x(x+1)=0
- 6x=0 or x+1=0
- x=0 or x=-1
For x=0
For x=-1
The solutions are
Graph attached
5(3)= 15
15/8= 1.875
According to the Order of Operations, multiplication and division should be done left to right. The problem can be rewritten as 5a/8.
Final answer: 1.875
