Answer:

24 square units

Step-by-step explanation:

The area of a parallelogram is given by the formula ...

A = bh

where A represents the area, b the length of the "base", and h the "height" measured at right angles to the base.

Here, it is convenient to use one vertical side of the figure as the base. You can count the grid squares to see that it is 8 units long.

The height is then the distance from one vertical side to the other. Again, you can count the grid squares to see that it is 3 units.

The area is the product of these dimensions:

A = (8 units)·(3 units) = 24 units^2

Help me please?!?!? Giving brainly!
Igoryamba

Answer:

Multiply input by 4.

Step-by-step explanation:

So, all we have to do is find the difference between the input/output.

So for the first one.

4y=1x

Divde both sides:

1y=1/4x

Next we have 16y=4x

Divide both sides:

1y=1/4x

Ok, so we now know that y is 1/4x

Or in otherwords, 4x is 1y.

Remember x is input, and y is output.

So we can think of this as the input times 4 equals the output.

This seems to be the second answer.

Hope this helps!

For what value of k are the roots of the quadratic equation kx (x-2)+6=0 equal?​
ser-zykov [4K]

Answer:

\boxed{\sf k=6}

Step-by-step explanation:

\sf kx (x-2)+6=0

Expand brackets.

\sf kx^2 -2kx+6=0

This is in quadratic form.

\sf ax^2 +bx+c=0

Since this is for equal roots:

\sf b^2 -4ac=0

\sf a=k\\b=-2k\\c=6

\sf (-2k)^2 -4(k)(6)=0

\sf 4k^2-24k=0

\sf 4k(k-6)=0

\sf 4k=0\\k=0

\sf k-6=0\\k=6

Plug k as 0 to check.

\sf \sf 0x^2 -2(0)x+6=0\\6=0

False.

So that means k must equal 6.
