Using the distance formula,
Since ABCD has two pairs of opposite congruent sides, it is a parallelogram.
Answer:
Step-by-step explanation:
1 + 3 = 4
so find the point 1/4 of the way from (-1, 2) to (7, 8)
x coordinate
Δx = ¼(7 - (-1)) = 2
x = x₀ + Δx
x = -1 + 2 = 1
y coordinate
Δy = ¼(8 - 2) = 1½
y = y₀ + Δy
y = 2 + 1½ = 3½
(1, 3½)
We do like the following:
Set the first number is a and the second is b.
We have two equations: a+2xb=24, 2xa+b=21
And we have 2xa+4xb=48 or 2xa=48-4xb
So: 48-4xb+b=21 or -3xb=21-48=-27 and we got b=-27:(-3)=9 and a= 6
a=6 and b=9

Answer:
56
Step-by-step explanation:
Put the values where the variables are and do the arithmetic.
3ab +b = 3(9)(2) +2 = 56
1) Which of the following is an example of a dilation?
The correct answer is A) The hearts.
2) If triangle ABC is reflected across line m, the new coordinates will be located at A'(2, -4) B'(7,-7) C'(-2, -7).
The answer is False.
I hope this helps! I can't really see #3. Sorry. But I got #'s 1 & 2 though!
