You can find the perimeter by finding the distance between all three points and then adding the sums together.
From (-1, 4) to (2, 7)
d=√(x₂-x₁)²+(y₂-y₁)²
d=√(2-(-1)²+(7-4)²
d=√(3)²+(3)²
d=√9+9
d=√81
d=9
From (2, 7) to (1, 5)
d=√(x₂-x₁)²+(y₂-y₁)²
d=√(1-2)²+(5-7)²
d=√(-1)²+(-2)²
d=√1+4
d=√5
d=2.24
From (1, 5) to (-1, 4)
d=√(x₂-x₁)²+(y₂-y₁)²
d=√(-1-1)²+(4-5)²
d=√(-2)²+(-1)²
d=√4+1
d=√5
d=2.24
2.24+2.24+9
=13.48
The perimeter of the triangle is 13.48.
Answer:
what is this???? i dont get it
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Because the y-intercept which is the last number days that it is crossing y at 3 and A is the only one that has a y-intercept of 3.
And now that you have that, you can work out the gradient which is 2
Multiply 6 by 1/2 to get 3
Ow you have :
3( h + 1) = 18
Distribute the 3:
3h + 3 = 18
Subtract 3 from both sides:
3h = 15
Divide both sides by 3:
H = 5
