Answer: 15 and one-half
Step-by-step explanation:
14/2 + 3(4) - (6.5 - 3)
Use PEMDAS
14/2 + 3(4) - 3.5
Use PEMDAS
7 + 12 - 3.5
Use PEMDAS
15.5
Perimeter of square = 4 x l
so ATC 4 x l = 240
= 240/40= l
so 60 = l
the answer is 60 inches.
Slope of perpendicular is -1/3.
Then equation is
y-5=(-1/3)(x+9)
Answer:
D
Step-by-step explanation:
Either try all the numbers and see which ones work or do the following.
Times both sides by 2x-5.
3=x(2x-5)=2x^2-5x
Rearrange and solve the quadratic. I will factorise.
2x^2-5x-3=0
(2x+1)(x-3)=0
so x = -1/2 or 3
24/5 = (20 + 4)/5 = 20/5 + 4/5 = 4 + 4/5
= 4 4/5
