Answer:
Step-by-step explanation:
To solve this problem, first you have to isolate it on one side of the equation. Remember to solve this problem, multiplication property of equality is multiply both sides of an equation the same number doesn't change the equation.
First, switch sides.
Next, multiply 14 from both sides.
Solve.
Therefore, the correct answer is z=84.
Answer:
The graph if h(x) =2x-3 will have the same slope, but placed lower on the graph, because it's y intercept is -3, while the y-int of f(x) is 0, which is higher up on the y axis
Answer:
Length of the final sides: 6 cm and 16 cm
Step-by-step explanation:
The lengths of the sides of the original box are
Later, a piece of tin is cut out from each corner; the piece cut out has the shape of the square: we can call the length of its generic side x. Therefore, the dimensions of the box will now be:
We also know that the area is
And the area can be written as product of length and width, therefore:
So we find:
Solving for x,
Which has two solutions:
x = 13 cm (this is larger than the initial length of the width, therefore we discard it)
x = 2 cm
So, the length of the new sides are
