It seems there are always three pairs: SSS, side side side; SAS, side angle side; ASA, angle side angle.
For a right triangle (HL, LL) it seems there are only two items needed, but that's because we already know one angle (it's right).
Once we have congruent triangles, all the corresponding parts are congruent. That's three sides and and three vertices, so I'd answer six. Of course almost everything about the triangles is the same, the area, the perimeter, etc.
Answer:
infinite solutions
Step-by-step explanation:
3(12x2+x+1)+12(12x2+x+1)=15(12x2+x+1)
Combine like terms
3(12x2+x+1)+12(12x2+x+1)=15(12x2+x+1)
15(12x2+x+1) = 15(12x2+x+1)
Divide by 15
(12x2+x+1) = (12x2+x+1)
Since they are the same
x can be any real value
y - y₁ = m(x - x₁)
y - (-1) = -1¹/₂(x - 3)
y + 1 = -1¹/₂(x) + 1¹/₂(3)
y + 1 = -1¹/₂x + 4¹/₂
- 1 - 1
y = -1¹/₂x + 3¹/₂
4x + y - 2 = 0
+ 2 + 2
4x + y = 2
4x - 4x + y = -4x + 2
y = -4x + 2
y - y₁ = m(x - x₁)
y - (-3) = -4(x - 4)
y + 3 = -4(x) + 4(4)
y + 3 = -4x + 16
- 3 - 3
y = -4x + 13
2x - 3y - 5 = 0
+ 5 + 5
2x - 2x - 3y = -2x + 5
-3y = -2x + 5
-3 -3
y = ²/₃x - 1²/₃
y - (-3) = -1¹/₂(x - 4)
y + 3 = -1¹/₂(x) + 1¹/₂(4)
y + 3 = -1¹/₂x + 6
- 3 - 3
y = -1¹/₂x + 3
3.89 rounded to the nearest tenth is 3.9
You go to the tenths place which is 8, and then go to the number next to it. 9 is greater than 5, so you have to round up.
You regroup and get 3.9
3.9
Answer:
you'd get the expression 6.37+7.8k
