For a right triangle with legs legnth a and b and hyptonuse c
a²+b²=c²
ok, so side lengths (legs) re 5 and 6, find c or x (c=x=hypotonuse)
6²+5²=x²
36+25=x²
61=x²
sqrt both sides
√61=x
well, the equation would be a²+b²=c² or
Answer:
7 units
Step-by-step explanation:
Please refer to the image attached with this answer.
Our initial line was CD joining points (-1,2) and (6,2).
It is now pulled down by 4 units , to new points
(-1,-2) and (6,-2)
Now we again shift this line by 2 units to the left. The new coordinates thus would be C'(-3,-2) and D'(4,-2)
Hence the distance C'D' = 4-(-3) = 4+3 = 7 UNITS
Hence the length of the line will be 7 units.
It is observed that the length of the line segment remains the same as it was of the original line. as the translation is uniform.
Answer:
x = 7
Step-by-step explanation:
Let x = the number. Then
"Triple a number" means 3x
"is the same as" means =
"double the number increased by 5" means 2x + 7
∴ 3x = 2x + 7
Subtract 2x from each side
x = 7
The answer is x = 7.
Check:
3 × 7 = 2 × 7 + 7
21 = 14 + 7
21 = 21
OK.
2(3x-1)=8x-20
SIMPLY
6x-2=8x-20
SUBTRACT 6x ON BOTH SIDES
-2=2x-20
ADD 20 TO BOTH SIDES
18=2x
DIVIDE 2 ON BOTH SIDES
X=9

16.) 38.25= 4.25h
divide by 4.25 on both sides
h=9
17.)214= 1/3x
divide by 1/3 on both sides
x= 642
18.)70= 2x
divide by 2 on both sides
x=35
19.)18.69= 5.25+1.68x
subtract 5.25 on both sides
13.44=1.68x
divide by 1.68 on both sides
x=8
