Answer:
9
Step-by-step explanation:
So first I created 2 distance forumlas and set them equal to each other
then I simplified them
when k = 9, the two distances are equal
A=1/2 (b1+b 2)(h) is the area of a trapezoid
Answer:
Your answer would be G, since point G is opposite of point B, and is a ray.
Step-by-step explanation:
Answer:
15 and 1
Step-by-step explanation:
x and y are two numbers.
Two equations:
x · y = 15
x + y = 16
Rearrange one of the equations (I'll rearrange the sum equation):
x + y = 16
x = 16 - y
Substitute that to the other equation and solve for y:
x · y = 15
(16 - y) · y = 15
16 - y · y = 15
16 - y² = 15
-y² = 15 - 16
-y² = -1
y² = 1
y = √1
y = 1
Now substitute that to any of the equation and solve for x (in here, I'll choose the multiplication one):
x · y = 15
x · 1 = 15
x = 15
Now verify:
15 · 1 = 15
15 + 1 = 16
This is correct
If a square has an area of 45 square units its side has a length of
units. Is that a perfect length? I don't know, but I know it's perfect for a square whose area is 45.
