Answer:
5, 10, 11
Step-by-step explanation:
You could actually solve this problem 2 ways. You could use the pythagorean theorem, if you could confirm it was a right triangle.
But since they give you the perimeter, that will be the easy way.
Perimeter means all the sides added together will be 26
(x) + (x+5) + (2x+1) = 26
Now combine like terms
4x + 6 = 26
Subtract 6 from both sides
4x = 20
Divide both sides by 4
x = 5
Now we can plug the x back in the find the length of each side
(5) = 5
(5) + 5 = 10
2(5) + 1 = 11
Answer:
The left side 5
The bottom 10
The slanted side 11
Step-by-step explanation:
To find the perimeter of the triangle, add up the side lengths
x+ 2x+1 + x+5 = 26
Combine like terms
4x+6 = 26
Subtract 6
4x+6-6 =26-6
4x=20
Divide by 4
4x/4 = 20/4
x=4
The left side x = 5
The bottom x+5 = 5+5 = 10
The slanted side = 2x+1 = 2*1 +1 = 10+1 =11

Answer:
-2. 46
- 9.54
Step-by-step explanation:
- 2x²+12x-7=0
- 2x²+12x+18= 25
- 2*(x²+6x+9)=25
- 2*(x+6)²= 5²
- x+6= 5√2/2 ⇒ x= 5√2/2 -6 ≈ -2. 46
- x+6= -5√2/2 ⇒ x= -5√2/2 -6 ≈ - 9.54
Answer:
395.85
Step-by-step explanation:
If the diameter is 12, then the radius must be 6. Following the formula of pi: 2 * pi * radius, our result is 37.7. 37.7 * 10.50 is 395.85
I really hope this helps. My memory of circles and pi isn't the best.
