Answer:
19
Step-by-step explanation:
The equation has "absolute value" , "addition", "subtraction", "division", and "multiplication", and "parenthesis".
The order we follow here would be:
PEMDAS, which is "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction"
Also, note, we can do absolute value first, before these.
Now let's simplify using PEMDAS:
So the answer is 19 (note: i used "/" sign for "division")
Answer:
Step-by-step explanation:
120=x²×h=x×xh
xh=120/x
surface area A(x)=2x²+4x×h=2x²+4xh=2x²+4×120/x=2x²+480/x
(ab + 4a - 6) - (ab - 6) = ab + 4a - 6 - ab + 6 = (ab - ab) + (6 - 6) + 4a = 4a
Answer:
x=3, y=0.8
Step-by-step explanation:
8x+5y=28
4x+5y=16
Subtract the second simultaneous equation from the first.
You are left with: 4x=12
12/4=3
x=3
Substitute this back into one of the equations.
8(3)+5y=28
8*3=24
28-24=4
4=5y
4/5=0.8
y=0.8
