Greatest error is half smallest measuring unit. It's measured to 0.1 cm , half that is 0.05 cm answer D.
Answer:
<h2> There is no slope.</h2>
Step-by-step explanation:

It means that for a line passing through two points to have the slope, the x-coordinates of these point have to be different.
(-4, 0) and (-4, -10) means x₁ = x₂ = -4, <u>so there is no slope.</u>
{the line is parallel to Y-axis, and has an equation: x=-4}
1/2 x base x height
1/2 x 6 x 8 = 24 (a)
Answer:
w = 17
Step-by-step explanation:
Isolate the variable, w. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operations, and stands for:
Parenthesis
Exponents (& Roots)
Multiplications
Divisions
Additions
Subtractions

First, subtract 13 from both sides of the equation:
4w + 13 (-13) = 81 (-13)
4w = 81 - 13
4w = 68
Next, divide 4 from both sides of the equation:
(4w)/4 = (68)/4
w = 68/4
w = 17
w = 17 is your answer.
