Answer:
3039007
Step-by-step explanation:
V= 13
Substitue (v) for 13
7253(8*4(13))
Go by the rules be PEMDAS
First you the parentheses
4 times 13= 52
52 times 8= 416
Now you just multiply the two numbers
416 times 7253= 3039007
Answer:
Step-by-step explanation:
P = (-4, 3)
Reflecting across the y axis negates the x value
P₁ = (4, 3)
Reflecting across the x axis negates the y value
P' = (4, -3)
option D
In scientific notation: 8.74*10^-7
B. All sides are equal and each side is at a 60 degree angle.
