The reduction was 1/5.

Because you are given the reduced values, multiply the reduced value by the inverrse of the factor:

Inverse of 1/5 = 5

Height = 3 x5 = 15

Base = 5 x 5 = 25

The base is 25

HELP WITH NUMBER 13 please
amid [387]

Answer: QE = 10

Step-by-step explanation: To solve this problem, it's important to understand that the diagonals of a parallelogram bisect each other.

This means that E is the midpoint of diagonal SQ.

So we can setup the equation x² + 9x = 4x + 6.

To solve this polynomial equation, set it equal to zero first.

So we have x² + 5x - 6 = 0 and we get (x + 6)(x - 1) = 0

when we factor the left side of the equation.

So this means that x = -6 or x = 1.

However, -6 will give us a negative length when we plug it in

to find QE so this will not work.

However, plugging 1 in will give us 10 as a length so QE = 10.

Graph f(x) = |x - 6| -4
LekaFEV [45]

Answer:

Step-by-step explanation:

Graph the parent function y = |x|.  This graph has a v shape with vertex at (0, 0) and opens up.

Now translate the entire graph 6 units to the right.  The vertex will now be at (6, 0).

Finally, translate this most recent graph 4 units down.  The vertex will now be at (6, -4).
