The width of a rectangle is 1 units less than the length. The area of the rectangle is 20 units. What is the width, in units, of the rectangle?

4

Step-by-step explanation:

Area is found by multiplying the length and width.

Let's think about the factors of 20.

The only ones are

4x5 and 1x20

There's only one set of lengths and widths where the width is 1 less than the length, 4 and 5.

Remember, the width is always the smaller number. So, the width must be 4.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
