Substitute the variable terms with the coordinates and the equation is
3=1/3(5)+b
solve for b
Answer:
r= -6
Step-by-step explanation:
first we move the terms
6r-7r = 13-7
-r= 6
and once we change the signs
r= -6
hope it helps pls mark me as brainliest
The sum of the angles should be 180, so x+ (x+10) + (x+5) = 180. This simplifies to 3x + 15 = 180, so 3x = 165, so x=55.
Find the area of all the sides and add together
area of base: = l x w = 5 x 5 = 25
Area of triangle: bh/2 = 5 x 6/2 = 15, but you have 4 of them so you multiply by 4 and get 60
60 + 25 = 85
