Answer: 39
Step-by-step explanation:
x(z+3)+1+3-y
plug in the values given for each variable
6(2+3)+1+3-(-5)
use pemdas to solve
6(5)+1+3+5
30+1+3+5
31+8
39
Answer:
18xy-2x-5y-8
Step-by-step explanation:
Просто умножьте,то что было в скобках
The answer is really 4 2/3 dozen cookies or 56 cookies.
96 - 40 = 56 cookies
8 - 3 1/3 = 4 2/3
24/3 - 10/3 = 14/3 = 4 2/3 dozen or 56 cookies
While using the Midpoint formula, you are finding x and y values in the middle of two points.
When you use the distance formula, you are finding the actual length of a line that is connecting two points.
I hope that this helps :)
You use Pythagorean theorem...a^2+b^2=c^2
a=12ft
b=47-31.. height of the triangle
c=distance between two roof tops
(12)^2+(16)^2=c^2
144+256=c^2
400=c^2, take square root of both sides
c=20ft
