x² + 5x - 6 can be expressed as (x + 6)(x - 1).
The scale model of a building 3 inches tall if the building is 90 feet tall is 2:5
<h3>Scaling of measurement</h3>
Scaling is the way of enlarging or reducing the image of an object.
Given scale model of a building is 3 inches, if the building is 90feet tall, to write the scale;
Convert both measures to same units
Since 1 feet. = 12 in
90 feet = 90/12 in = 7.5 in
Take the ratio
3 : 7.5 = 30: 75
Reduce to lowest term
30: 75 = 2 : 5
Hence the scale model of a building 3 inches tall if the building is 90 feet tall is 2:5

The factored expression would look like this : 3(x+8)(x-8)
Answer:
probably maybe 5
Step-by-step explanation:
it looks like you want to multiple 2 to each side to eliminate that denominator. then maybe subtract that 1 away to isolate k. it might equal 5 I'm doing it in my head
